Question

Select the correct answer.

What is the solution for x in the equation?

16x − 4 + 5x = -67

Answer 1

you take the -4 you add it onto the -67 then you get 16x + 5x = -63 you combine like terms (16x and 5x) then you get 21x=-63 you have to factor the x out so divide the 21 to the -63 and you should get x = -23

Answer 2

x = -3

Explanation:

16x - 4 + 5x = -67 Combine like terms

21x - 4 = -67 Add 4 to both sides

21x - 4 + 4 = -67 + 4

21x = -63 Divide both sides by 21

x = -3
