20² + 6 (9 + 3) = 400 + 6 (12) = 400 + 72 = 472
Answer:
-14x - 9y = 6
Step-by-step explanation:
If we subtract the second equation from the first, we will get this setup:
(-7x - y) - (7x + 8y) = -14x - 9y
0 - (-6) = 6
So the resulting equation -14x - 9y = 6
So (2x+5) and (x+55) are equal to each other, so
2x+5 = x+55
x+5 = 55
x = 50
Solve for d by simplifying both sides of the equation, then isolating the variable.
D= -19/3
You get the answer by counting the units, the answer is 3.
