x = 22
Step-by-step explanation:
Note that the angles are directly next to each other, and, when combined, forms a straight line, in which it's angle measurement is 180°. Set both terms equal to 180°:
5x + 3x + 4 = 180
First, combine like terms:
(5x + 3x) + 4 = 180
8x + 4 = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, subtract 4 from both sides of the equation:
8x + 4 (-4) = 180 (-4)
8x = 180 - 4
8x = 176
Next, divide 8 from both sides of the equation:
(8x)/8 = (176)/8
x = 176/8 = 22
x = 22 is your answer.
