Question

Solve by the substitution method
2x-10=-y
3x-y=0

Answer 1

Minus the 2x on the first equation to get
-2x-y=-10
3x-y=0

Answer 2

Lets get rid of the y so multiply a - on the 1st equation to get
2x+y=10
3x-y=0
Then it will be
5x=10
Divide the 5 on both sides
x=2
plug the 2 on one of the equations
3(2)-y=0
6-y=0
Subtract the 6
-y=-6
Divide the -
y=6
So it is
x=2 & y =6

Answer 3

Do you get it?

Answer 4

Hello?

Answer 5

Good use of the elimination method, but to answer the problem as posed, change the second equation to 3x=y and put it into the first equation

2x-10=-3x then 5x=10 then x=2 and y =6. Substitution method.

Answer 6

(x,y)=(2,6) (almost forgot to give the answer!!)
