Answer:
use the combination method
Step-by-step explanation:
x - 2y = -13
+ 5 x + 2y = -17
since 2y is in both equations you cancel them out.
5x + x = 6x
-2y + 2y = 0
-13 + (-17) = -30
put it back into the equation
6x + 0 = -30 or 6x = -30
6x ÷ 6 = x
-30 ÷ 6 = -5
x = -5
then plug into the equation x - 2y = -13 and 5x + 2y = -17
-5 - 2y = -13
-13 + 5 = -8
-2y = -8
y = 4
x = -5 and y = 4
Answer: 6rx = x^2 -5
