I am trying to solve the sytems of equations using the elimination method.

2x+4y=10

-3x+3y=-6

I tied multiplying the first equation by 2 and the second by 4. Then I tried multiplying the first equation by -3 and the secondy by 3.

The book says the answers are 3,1.

I am not getting these answers.

Try to multiply first equation by 3 and second equation by 2. You will end up with 6x and -6x, you can eliminate those and then use the substitution method to find y.

Multiply the second equation by 2/3

2x+4y=10

-2x+2y=-4

add the equations

6y=6

y=1

Put that y back into either equation, and solve for x.
