3x + 10(x + 4) = 170

While we're all sitting here looking at it, let's also go ahead and solve it.

(That means: Find out what 'x' is.)

Eliminate parentheses from the left side:

3x + 10 x + 40 = 170

Combine the 'x' terms on the left side:

13x + 40 = 170

Subtract 40 from each side:

13x = 130

Divide each side by 13:

x = 10
