1 + 6x = -13 - x
A 1-3 B) (-12)
c) 1-2 D) {3}

-2

Step-by-step explanation:

1 + 6x = -13 - x

Add x to both sides to eliminate x on the right

1 + 6x + x = -13 - x + x

1 + 7x = -13

Subtract 1 from both sides to eliminate 1 on the left side

1 - 1 + 7x = -13 - 1

7x = -14

Divide both sides by 7 to isolate x

7x/7 = -14/7

x = -2

A) 1-3

Step-by-step explanation:

1 + 6x = -13 - x

+13        +13

14 + 6x = -x

    -6x      -6x

14 = -7x

-2 = x
