Question

Find the solution of this system of equations -7x-6y=59 and -8-6y=58

Answer 1

-7x - 6y = 59.....multiply by -1
-8x - 6y = 58
----------------
7x + 6y = -59 (result of multiplying by -1)
-8x - 6y = 58
---------------add
-x = -1
x = 1

-7x - 6y = 59
-7(1) - 6y = 59
-7 - 6y = 59
-6y = 59 + 7
-6y = 66
y = -66/6
y = -11

solution is (1,-11)
