3(x + 1) - 8 = 5 + x


3x + 3 - 8 = 5 + x


3x - 5 = 5 + x


3x - x = 5 + 5


2x = 10


x = (10)/(2)


x = 5

Answer:

x=5

Explanation:

solve brackets first=

3x+3-8=5+x

3x-5=5+x (simplify the like terms)

3x-x=5+5 ( take to one side; the like terms)

2x=10 (simplify)

x=10/2 (take to one side like terms)

x=5 (soo. answer)
