Answer 8

this is harder than that.. i dunno wat to plug in...

Answer 9

4x+6y=-9
-3x-10y=-11

y = (-9 - 4x)/6
y = (-11 + 3x)/-10

y = y

-10(-9-4x) = 6(-11+ 3x)

90 + 40x = -66+18x

40x-18x = -66-90

22x = -156

x = -156/22 = -78/11

Good luck finding y

Answer 10

solve the first equation for x:


4x+6y=-9
x = (-9 -6y)/y

Now, substitute this equation in eq2:


-3x-10y=-11
-3( (-9 -6y)/y)-10y=-11
