Answer:

X= - 1 /14

Step-by-step explanation:

combine like terms

7x+=2x + 2 - 9x

7x + 3 = -7x + 2

Subtract 3 from both sides

7x + 3 = - 7x + 2

7 x + 3 - 3 = - 7x + 2 - 3

Simplify

7x + 3- 3 = - 7x + 2 - 3

7x = - 7x + 2- 3

7x = - 7x - 1

Add 7x to both sides

7x = - 7x - 1

7x + 7x = - 7x - 1 + 7x

Simplify

14x = - 7x - 1 + 7x

14x = - 1

Divide both sides by the same factor

14x = - 1

Cancel terms that are in both the numerator and denominator

14x = - 1

___ ___
