Question

What is the solution for x in the equation? 16x − 4 + 5x = -67

Answer 1

`\huge \boxed{x = -3}`

Explanation:

`16x - 4 + 5x = -67`

Combine like terms.

`21x - 4 = -67`

Add 4 to both sides.

`21x = -63`

Divide both sides by 21.

`x = -3`

Answer 2

x = -3

Explanation:

16x − 4 + 5x = -67

Combine like terms

21x -4 = -67

Add 4 to each side

21x-4+4 = -67+4

21x = -63

Divide each side by 21

21x/21 = -63/21

x = -3
