Answer:
well angle d equals 107 so the difference would be 62
Step-by-step explanation:
X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
2x - 2x - 7 = -7 implies that,
-7 = -7
This means that the equation has infinitely many solutions.
The answer is D because you have to sneer what is in the parentheses first
