Answer:

x = -2

Explanation:

Divide both sides by 3

3 (2x + 5)/3 = 3/3

Simplify

2x + 5 = 1

Subtract 5 from both sides

2x + 5 - 5 = 1 - 5

Simplify

2x = -4

Divide both sides by 2

2x/2 = -4/2

Simplify: 2x/2

Divide the numbers: 2/2 = 1

= x

Simplify: -4/2

Apply the fraction rule: -1/b = -a/b

= - 4/2

Divide the numbers: 4/2 = 2

= -2

x = -2
