X + 5 = 2x - 25 //isosceles △
2x - x = 25 + 5
x = 30°
x + 5 + 9y + 28 = 180 //adjacent angles on a straight line add up to 180
x + 9y + 33 = 180
x+ 9y = 147
Since we know that x is 30, we will sub x = 30 into the equation to find y
30 + 9y = 147
9y = 147 - 30
9y = 117
y = 13

Answer: x = 30; y = 13

Step-by-step explanation:
Only D has a chance of being correct. 7x means you multiply 7 and whatever x is together.
A and B look like they are added.
C looks like some sort of subtraction has taken place.
D: - 1 * 7 = - 7
4*7 = 28
5*7 = 35
