Solve the equation: 15+ 5x = -x - 3

x = -3

Step-by-step explanation:

to solve the equation we will collect the like terms and evaluate

15 + 5x = -x-3

15 + 5x + x = -3

15 + 6x = -3

6x = -3 - 15

6x = -18

divide both side by  the coefficient of x which is 6

6x/6 = -18/6

x = -3

to check if your answer is correct we will  put the value of x = -3 into the  equation and we will  check if the right handside equals to the left handside.

15 + 6x = -3

15 + 6(-3) = -3

15 - 18 = -3

-3 = -3 proved
