Answer:

x - 10 = 75, or the second one

Step-by-step explanation:

The first, third, and fourth one is all equations that can help determine the measure of angle C, not D.

Hope this helps!!

Which one is it A. B. C. or D.

nadya68 [22]

7x + 2y = 2
2x - y = 10

2y = - 7x + 2
- y = - 2x + 10

2y = -7x + 2
y = 2x - 10

$y=\frac{-7x+2}{2}$
y= 2x - 10

y = -3.5x + 1
y = 2x - 10

Now, let's find "x" first by doing a substituion !

2x - 10 = - 3.5x + 1
y = 2x - 10

2x + 3.5x = 1 + 10
y = 2x - 10

5.5x = 11
y= 2x - 10

$x = \frac{11}{5.5}=2$
y= 2*2 - 10 = 4 - 10 = -6

In short, the answer would be : y = -6 (Option B).

Hope this helps !
