Question

8x+18+21=-187

Answer 1

first subtract -18 on both sides.

Answer 2

then subtract -21 on both sides.

Answer 3

You need to remove +18 and +21 from the equation. Do so by subtracting said numbers from both sides, leaving you with 8x = (whatever this number may be after subtraction)

Then, divide that number by 8, giving you x = your answer.

Answer 4

and at last divide both sides by 8

Answer 5

is X= -113/4
