Question

Solve: 6 -x= 4(5 + x)- 4

OA. x=-2
O B. There are infinitely many solutions.
O C. a =-
OD. X=-5

Answer 1

x = - 2

Explanation:

Given

6 - x = 4(5 + x) - 4 ← distribute and simplify right side

6 - x = 20 + 4x - 4

6 - x = 16 + 4x ( subtract 4x from both sides )

6 - 5x = 16 ( subtract 6 from both sides )

- 5x = 10 ( divide both sides by - 5 )

x = - 2
