OpenStudy (anonymous):

Im guessing this a simple substitution question

OpenStudy (anonymous):

ok so since y= 3x -24 we can plus the value of y into the other equation 5x-y=8

OpenStudy (anonymous):

notsure how to do thiss can you help me

OpenStudy (anonymous):

so it would look like this 5x-(3x-24)=8

OpenStudy (anonymous):

and now we just solve for x

OpenStudy (anonymous):

5x-(3x-24)=8 5x-3x+24=8 2x=8-24 2x=-16 2x/2=-16/2 x=-8
