Question

select the best possible first step to solving the following system by first eliminating the y variable. 4x+5y=-8 3x+2y=1

Answer 1

I'd solve for y first.

Answer 2

for both equations

Answer 3

That, to me, would be the way

Answer 4

so you would have...

y = -(8+4x)/5

and

y = (1-3x)/2


Set y = y

and then you're left with:

-(8+4x)/5 = (1-3x)/2

Answer 5

Then cross multiply and finish solving for x
