Answer:
Step-by-step explanation:
-3x + 3y = 6.......(1)
y= 4x + 5............(2)
Putting (2) in (1)
-3x + 3(4x + 5) = 6
-3x + 12x + 15 = 6
9x = 6 -15
9x = -9
x = -9/9
x = -1
Putting x in (2)
y= 4x + 5
y = 4(-1) + 5
y = -4 + 5
y = 1
-3x+3*(4x+5)=6
-3x+12x+15=6
9x=6-15
9x=-9
x=-9/9
x=-1
y=4x+5
y=4*(-1)+5
y=-4+5
y=1
