Question

What is the value of x in the equation 2x+7=1

Answer 1

Isolate x: 2x=-6
x=-3

Answer 2

First....we need to do inverse operation

Subtract 7 from both sides.

2x+7=1
    -7   -7

2x=-6

Now, we need to divide 2 by both sides to isolate x.

2x=-6
2x/2=-6/2
x=-3

Our final answer is that x= -3
