How many solutions does an inequality have?
The solution set of a single linear inequality is always a half-plane, so there are infinitely many solutions..
How do you make an inequality true?
To determine whether an inequality is true or false for a given value of a variable, plug in the value for the variable. If an inequality is true for a given value, we say that it holds for that value. Example 1. Is 5x + 3≤9 true for x = 1 ?
What is the golden rule for solving equations?
Do unto one side of the equation, what you do to the other! An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
Which is the solution to the inequality?
A “solution” of an inequality is a number which when substituted for the variable makes the inequality a true statement. When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x=8 is a solution of the inequality.
How do you solve 2 step equations?
Solving Two-Step Equations1) First, add or subtract both sides of the linear equation by the same number.2) Secondly, multiply or divide both sides of the linear equation by the same number.3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.More items…
What is a 2 step equation?
A two-step equation is an algebraic equation that takes you two steps to solve. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
What is a 2 step equation example?
Solution: In the equation 3x – 2 = 16, notice that the variable is being multiplied and has a term being subtracted. To isolate the variable, we need to add 2 to both sides and then divide both sides by 3.
Are the solution of each inequality real numbers Why?
Answer. Step-by-step explanation: If the inequality states something untrue there is no solution. If an inequality would be true for all possible values, the answer is all real numbers.
What are the rules for solving equations?
A General Rule for Solving EquationsSimplify each side of the equation by removing parentheses and combining like terms.Use addition or subtraction to isolate the variable term on one side of the equation.Use multiplication or division to solve for the variable.
What are the four steps for solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.
How do you simplify equations?
To simplify any algebraic expression, the following are the basic rules and steps:Remove any grouping symbol such as brackets and parentheses by multiplying factors.Use the exponent rule to remove grouping if the terms are containing exponents.Combine the like terms by addition or subtraction.Combine the constants.
