Isolate the variable

Addition and subtraction are inverse operations. So you can solve addition by subtracting.
You would use inverse operations. I had this on my math homework and got it correct so I know this! ============================================== Good for you ! You know what you said, but you don't know what you know. I'd say that you use the Golden Law: "You must always do exactly the same thing to both sides of an equation."
Because you need to use inverse operations and the opposite of multiplication is division.
Inverse operations are just the operation backwards. Example: You do the operation of going to school. The inverse would be going from school to home. Now that you understand the concept of inverse, you just have to apply it to numbers. If you start with 6, and add 4 to get to 10, then the inverse would be to subtract 4 from 10 which would put you at your starting number. *Remember that any number multiplied by its reciprocal is 1.
A two-step equation is a mathematical equation that requires two steps to solve. It involves applying inverse operations to isolate the variable on one side of the equation. The goal is to determine the value of the variable that satisfies the equation.
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
equation
In an inverse relationship, one variable decreases while the other increases. As an equation, a basic inverse relationship looks like x = 1/y.
That depends a lot on the type of equation. A common method, that works for many of the simpler equations, is to do one or more operations to isolate the variable you want to solve for on the left side. The basic principles are (1) whatever you do on one side of the equation, you have to do on the other side as well; (2) choose your operations so as to get rid of anything that is not the variable. Often this involves using inverse operations. As an example, solve: 2x + 3 = 15 The idea is to isolate the "x" on the left. First, to get rid of the "+3", do the inverse operation - subtract 3 on both sides. The result is: 2x = 12 Next you want to get rid of the "2". Since there is a multiplication, you do the inverse operation - divide by 2. The result is: x = 6
