Question

Solve using the elimination method. -3x + 4y = 1

-6x + 6y = -3 i got as far as eliminating x so I have 10y=-3 ?

Answer 1

I mean 14y=-3 is this correct?

Answer 2

(-3x+4y=1) <<<Multiply this by -2 to elimiinate x
-6x+6y=-3

Answer 3

right so therefore the problem becomes -2y=1

Answer 4

No!, You're left with -2y=-5

Answer 5

oh ok ad both sides gotcha

Answer 6

then it would be y=-5/2 is this correct?

Answer 7

y=5/2, dividing a negative by a negative yields a positive

Answer 8

ok then I just plug 5/2 into both equations to solve for x correct?

Answer 9

Plug it into 1 will work
