Question

isolate the variable on the following problem. show your work.

-2=-4+x​

Answer 1

Answer:

x=2

Step-by-step explanation:

Add 4 to both sides:

-2=-4+x​

-2+4=-4+4+x​

2=x

Answer 2

Answer:

$x = 2$

Step-by-step explanation:

First we must add 4 to both sides.

$-2 = -4 + x$

+4      +4

-4 + 4 = 0

-2 +4 = 2

Isolating a variable means that it is alone on its side of the eqation.

$2 = x$

x is now isolated and we also have the solution for it.

$x = 2$
