Answer:
y = 
Step-by-step explanation:
Given
x(y + 2) = 3x + y ← distribute parenthesis on left side
xy + 2x = 3x + y ( subtract 2x from both sides )
xy = x + y ( subtract y from both sides )
xy - y = x ← factor out y from each term on the left side )
y(x - 1) = x ← divide both sides by (x - 1)
y =

Answer:
x = 12
Step-by-step explanation:
Triangle DGH is isosceles with base angles at D and G. The external angle 134° at H is the sum of those two base angles, so we have ...
2(5x+7) = 134
5x +7 = 67 . . . . . divide by 2
5x = 60 . . . . . . . subtract 7
x = 12 . . . . . . . . divide by 5
The percent change from 36 to 63 is 63/36=1.75 (multiply by 100 to get a percentage) 175%
The percent change from 63 to 36 is 36/63=0.571=57.1%
