Answer: x=-3

<u>Add 3x to both sides</u>

<u></u>2x+15+3x=-3x+3x\\5x+15=0<u></u>

<u></u>

<u>Subtract 15 from both sides</u>

<u></u>5x+15-15=0-15\\5x=-15<u></u>

<u></u>

<u>Divide both sides by 5</u>

<u></u>5x/5=-15/5\\x=-3<u></u>

Answer:

x = -3

Step-by-step explanation:

2x + 15 = -3x     (try to move the x-terms to one side, add 3x to both sides)

2x + 15 + 3x = 0

5x + 15 = 0 (subtract 15 from both sides)

5x = 0 - 15

5x = -15    (divide both sides by 5)

x = -15 ÷ 5

x = -3

Hope this helps!
