1/3(24x - 54) = 11(x-4)+5
fiasKO [112]

Answer:

x = -7

Step-by-step explanation:

<u>Step 1:  Distribute</u>

1/3(24x - 54) = 11(x - 4) + 5

8x - 18 = 11x - 44 + 5

<u>Step 2:  Solve for x</u>

8x - 18 = 11x - 44 + 5

8x - 18 - 11x + 18 = 11x - 39 - 11x + 18

-3x / 3 = -21 / 3

x = -7

Answer:  x = -7
