Answer:
x = -31/6 or -5.16
Step-by-step explanation:
3(2x-3) + 49 -2 = 0
Distribute 3 through the parenthesis
3 (2x-3) + 49 - 2 = 0
6x - 9 + 42 - 2 = 0
Calculate the sum or difference
6x - 9 + 42 - 2 = 0
6x + 31 = 0
Move constant to the right side and change its sign
6x + 31 = 0
6x = -31
Divide both sides of the equation by 6
6x = -31
x = -31/6 or -5.16
