OpenStudy (radar):

I don't think it is 1.

OpenStudy (anonymous):

why not

OpenStudy (anonymous):

its =0.826....so it would round to -1

OpenStudy (anonymous):

-0.826*

OpenStudy (radar):

Because if you substituted 1 for y in both equations, x will result into two different values. If -1 was correct x in both equations would equal the same value.

OpenStudy (radar):

More like it.

OpenStudy (anonymous):

it was -1

OpenStudy (anonymous):

good try though

@radar

OpenStudy (radar):

3x - 8y = 10 x + 5y= -3 Eliminate x and solve for y multiply the 2nd equation by 3 3x - 8y = 10 3x +15y = -9 Now subtract the two equations eliminating x ------------- -23y = 19 Solve for y y= -19/23 = -.826 Rounding off to the nearest hundreth as problem requested; y=-83

If you want to round it off to -1, be my guest.
