SOLUTION: How do I solve for x and y when solving systems of equations by substitution y=6x-11 -2x-3y=-7 if I use the y=6x-11 into -2x-3y=-7 -2x-3(6x-11)=-7 do I multiply -3 and 6

Question 583938: How do I solve for x and y when solving systems of equations by substitution
y=6x-11
-2x-3y=-7
if I use the y=6x-11 into -2x-3y=-7
-2x-3(6x-11)=-7
do I multiply -3 and 6x?

ow do I solve for x and y when solving systems of equations by substitution
y = 6x-11
-2x-3y=-7
if I use the y=6x-11 into -2x-3y=-7
-2x-3(6x-11)=-7
Multiply 6x and -11 by -3
-2x - 18x + 33 = -7
-20x = -7 - 33
-20x = -40
20x = 40; multiply both sides by -1
x = 40/20
x = 2
:
Use the 1st equation to find y, replacing x with 2
:
Check your solutions in the 2nd equation, replacing x and y
