8-61.

Write an equation that represents each diagram below and find the value of the variable. Homework Help ✎

How are the two lines related?

How will this help you write an equation?

Because the two lines are equal, you can write the equation: *x* + *x* + 10 = 24

Combine like terms

2*x* + 10 = 24

Then solve for *x*:

2*x* = 14*x* = 7

*x* = 7

Use the same method as part (a).
