Solve for x.<br> 10x – 79 = 2x + 49<br> x = [?]
Harrizon [31]

Answer:

x = 16

Step-by-step explanation:

<u>Step 1:  Add 79 to both sides</u>

10x - 79 + 79 = 2x + 49 + 79

10x = 2x + 128

<u>Step 2:  Subtract 2x from both sides</u>

10x - 2x = 2x - 2x + 128

8x = 128

<u>Step 3:  Divide 8 from both sides</u>

\frac{8x}{8} = \frac{128}{8}

x = 16

Answer:  x = 16
