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
14x = - 1
