Question

Solve 4(x−9)=4(9+13x).

The solution is x=

Answer 1

Answer:

-1.5

Step-by-step explanation:

4x - 36 = 36 + 52x

We can make this into another equation.

72 + 52x = 4x

4x - 52x = -48x

-48x = 72

48x = -72

x = -72/48 = -1.5

Answer 2

Answer:

x = - $\frac{3}{2}$ = - 1.5

Step-by-step explanation:

Given

4(x - 9) = 4(9 + 13x) ← distribute parenthesis on both sides

4x - 36 = 36 + 52x ( subtract 52x from both sides )

- 4x - 36 = 36 ( add 36 to both sides )

- 4x = 72 ( divide both sides by - 4 )

x = $\frac{72}{-4}$ = - $\frac{3}{2}$ = - 1.5
