Answer:
the answer is (-15,13)
Step-by-step explanation:
try to solve for x on one equation, like 8x+9y=-3
x=-9/3y-3/8
plug x in for the next equation
6((-9/8y)-3/8)+7y=1
(-27y/4)-9/4+7y=1
y/4-9/4=1
y/4=13/4
y=13
now plug in the y value for any equation
6x+7(13)=1
6x+91=1
6x=-90
x=-15
So the answer to the system of equations is (-15,13)
