Answer:

x = 47

Explanation:

180 = x + (180 - 107) + (x + 13)

Subtract in the parenthesis.

180 = x + 73 + x + 13

Combine terms.

180 = 2x + 86

Subtract 86 from both sides.

2x = 94

Divide both sides by 2.

x = 47.

Proof:

180 = x + (180 - 107) + (x + 13)

180 = 47 + (180 - 107) + (47 + 13)

180 = 47 + 73 + 60

180 = 120 + 60

180 = 180
