7x+5y=-13
-2x=7y+26
solve by elimination

Step-by-step explanation:

7x + 5y = -13 multiply by 2

-2x - 7y = 26 multiply by 7

14x + 10y = -26 (result of multiplying by 2)

-14x - 49y = 182 (result of multiplying by 7)

add

-39y = 156

y = -156/39

y = -4

7x + 5y = -13

7x + 5(-4) = -13

7x - 20 = -13

7x = -13 + 20

7x = 7

x = 7/7

x = 1

check...

-2x = 7y + 26

-2(1) = 7(-4) + 26

-2 = -28 + 26

-2 = -2 (correct)...it checks out

answer is : x = 1 and y = -4 or (1,-4)
