What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?
zavuch27 [327]

Answer:

x = 2

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

13x - 2(8 + 5x) = 12 - 11x

<u>Step 2:  Distribute</u>

13x - 2(8 + 5x) = 12 - 11x

13x - 16 - 10x = 12 - 11x

<u>Step 3:  Solve for x</u>

13x - 16 - 10x + 11x + 16 = 12 - 11x + 11x + 16

14x / 14 = 28 / 14

x = 2

Answer:  x = 2
