Answer:

x = 21

Step-by-step explanation:

We know that a triangle equals to 180 degrees.

Combine like terms. (x + 3x) and (-4 + 100)

x - 4 + 3x + 100 = 180

Subtract 96 on both sides.

4x + 96 = 180

-96 -96

Divide 4 on both sides.

4x = 84

--- -----

4 4

And you get a solution of 21.

x = 21

<u>Check:</u>

Substitute 21 into x.

Add/Subtract from left to right.

21 - 4 + 3(21) + 100 = 180

17 + 63 + 100 = 180

80 + 100 = 180

180 = 180
