Answer:
x = 21
Explanation:
The 74 angle and y angle are supplementary which means they add up to 180 degrees, so 180 - 74 = 106
Then you know that y is equal to 4x + 22
so then you just set 4x + 22 equal to 106
then you subtract 22 from both sides which leaves you the equation 4x = 84
then you divide 84/4 which equals 21
