Answer:
C. Multiply the bottom equation by 2
Step-by-step explanation:
-2x+ 4y= 10
3x- 2y =-7
We want to multiply the second equation by 2
-2x+ 4y= 10
6x- 4y =-14
------------------
4x +0y = -4

Answer:
either you have 62.6 + 62.5 + 55
or you have 55 + 55 + 70
Step-by-step explanation:
There are only two possible answers.
Either 55 degrees is by itself and the two equal angles are something other than 55 in which case you would write it as
x + x + 55 = 180 Subtract 55 from both sides
2x + 55 - 55 = 180 - 55
2x = 125 Divide by 2
x = 125/2
x = 62.5
OR
There are 2 angles that are both 55
x + 55 + 55 = 180
x + 110 = 180
x = 70
