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.
To solve an equation for x, you need to isolate the variable on one side of the equation. Start by performing the inverse operation to undo any addition, subtraction, multiplication, or division. Once you have x by itself, the solution will be the value of x that satisfies the equation. Remember to follow the order of operations and be careful with signs to ensure accuracy in your answer.
Inverse operations are used to undo mathematical operations and isolate a variable. They help to solve equations and simplify expressions by moving operations to the opposite side of the equation. This allows us to find the value of the variable that makes the equation true.
To isolate a variable, you need to perform inverse operations to the ones applied to the variable. This involves moving constants to the other side of the equation, and then using operations like addition, subtraction, multiplication, or division to isolate the variable on one side of the equation.
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.

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

To solve a formula, you need to isolate the variable you are solving for by performing inverse operations. Start by simplifying the formula using the order of operations (PEMDAS), then move terms around to isolate the variable. Perform the inverse operations (addition/subtraction, multiplication/division) to solve for the variable. Remember to perform the same operation on both sides of the equation to maintain equality.
Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Addition and subtraction are inverse operations. So you can solve addition by subtracting.
