what is the inverse operation needed to solve for x subtraction addition multiplication or divison
The inverse operation needed to solve for x depends on the original operation used to obtain the equation containing x. If x was obtained by addition, the inverse operation would be subtraction. If x was obtained by subtraction, the inverse operation would be addition. If x was obtained by multiplication, the inverse operation would be division. And if x was obtained by division, the inverse operation would be multiplication.
To solve for x, the inverse operation that is needed depends on the original operation used.
If the original operation was addition (x + a = b), the inverse operation is subtraction (b - a = x).
If the original operation was subtraction (x - a = b), the inverse operation is addition (b + a = x).
If the original operation was multiplication (x * a = b), the inverse operation is division (b / a = x).
If the original operation was division (x / a = b), the inverse operation is multiplication (b * a = x).
Therefore, the inverse operation needed to solve for x can be subtraction, addition, multiplication, or division, depending on the original operation used.
To solve for x using the inverse operation, the inverse of subtraction is addition.
If you have an equation with x being subtracted from a number or expression, you can isolate x by adding the same value to both sides of the equation. This will undo the subtraction and help you solve for x.
For example, if you have the equation 5 - x = 10, and you want to solve for x, you can perform the inverse operation. Since x is being subtracted from 5, you can add x to both sides of the equation to eliminate the subtraction. This gives you:
5 - x + x = 10 + x
Simplifying, you get:
5 = 10 + x
Then, you can subtract 10 from both sides to isolate x:
5 - 10 = 10 + x - 10
-5 = x
Therefore, x = -5.
So, in this case, the inverse operation needed to solve for x was addition.
