Question

Solve by elimination. equation 1;3x-2y=16 & equation 2;6x+2y=20

Answer 1

Add the two equations.

Answer 2

add the two equations and you will see that the y's cancel each other out. Now you can find x. Once x is found, sub that back into either of the original equations and solve for y.

Answer 3

3x-2y=16
+ 6x+2y=20
=
(9x+36)/9
x=4


6(4)+2y=20
24+2y=20
-24 -24
=
(2y=-4)/2
y=-2


3(4)-2(-2)=16
12-(-4)=16
12+4=16
16=16


6(4)-2(-2)=20
24+(-4)=20
24-4=20

Answer 4

worked it out for ya
