What is a 1 step problem?
A one-step equation is an algebraic equation you can solve in only one step.
Once you’ve solved it, you’ve found the value of the variable that makes the equation true.
To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself..
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 equation has only one solution?
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
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.
What are the 4 steps to solving an equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division.
What is a 2 step math problem?
A two-step problem is a word problem that requires two operations to solve it, for example: I buy a magazine costing 83p and a pencil costing 45p. … The second operation is subtraction (£1.28 – 20p = £1.08).
What is a one step equation examples?
One step equation is an equation that requires only one step to be solved. You only perform a single operation in order to solve or isolate a variable. Examples of one step equations include: 5 + x = 12, x – 3 = 10, 4 + x = -10 etc. To solve this equation, divide both sides of the equation by 3.
