Question 127924: I would like to check my answer for the following equation.
I need to solve the following equations for y:
-5x-4y=4
3x+y=6
for the 1st equation -5x-4y=4 I got an answer of y=-5/4X-1
for the 2nd equation 3x+y=6 I got an answer of y= -3x+6

on the 1st equation I didnt know if I should multiply the fraction by 4 if I do so wouldnt I have to multiply the 1st part of the equation also. The answer just doesnt seem right may be because its a fraction. The 2nd equation I hope is right. If you could help I would greatly appreciate it. Thanks
