The equation given was: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87.

Using this equation, write the equation with fewer terms.

Answers

Answer:

x = 13

Step-by-step explanation:

(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

x + x + 3 + x - 2 + 3x + 9 - 1 = 87

6x + 9 = 87

6x = 87 - 9

6x = 78

x = 78/6

x = 13

X=13 hope that help you out buddy
