Answer:

Explanation:

We are given an equation( a math expression with an equal sign)

5+x-12=x-7

First things first, we need to combine any like terms(add/subtract) on the same side

A term is a number, variable, that is separated by a plus symbol or minus symbol.

Here 5 and -12 are similar terms so let combine them

5-12=-7 So the equation become

x-7=x-7

Step 2: Notice how the left hand and right-hand side are the same thus we do not need to solve this equation. But let do the work instead

x-7=x-7

x=x

Thus, the solution is All Real Numbers

Part B:

Substitute -4 for x in the original equation.

5+(-4)-12=-4-7

1-12=-4-7

-11=-11

Thus, the equation is true here.

Substitute 0 for x in the original equation

5+0-12=0-7

-7=-7

Equation is True Here

Try 5 for x as well

5+5-12=5-7

10-12=5-7

-2=-2

So equation is true as well.

Let me know if you have any questions or concerns.
