Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side 
6x - 7x = 2 + 3
-x = 5
x = -5

Answer:
y = 28 degrees
x = 28 degrees
Step-by-step explanation:
A right angle = 90 degrees
90 degrees - 62 degrees = 28 degrees
This is for both x and y because 62 degrees occupies both the right angles.
