-5x-3y=12
x-3y=-6
Solve x-3y=-6 for x
Add 3y to both sides
x-3y+3y=-6+3y
x= 3y-6
Substitute 3y-6 for x in -5x-3y=12
-5x-3y=12
-5(3y-6)-3y=12
Simplify both sides of the equation
-18y+30=12
Add -30 to both sides
-18y+30+-30=12+-30
-18y=-18
Divide both sides by -18
-18y/-18= -18/-18
y=1
Substitute 1 for y in x = 3y-6
x= 3y-6
x= (3)(1)-6
Simplify both sides of the equation
x= -3
Answer : B
( -3 , 1 )
