hint: if I apply the distributive property at the right side, I get: \[y - 13 = 4x - 8\] Now I add 13 to both sides, so I can write: \[y - 13 + 13 = 4x - 8 + 13\] please simplify

OpenStudy (anonymous):

y=4x+5

OpenStudy (michele_laino):

sorry, I meant this: I add 8 to both sides, so I get: \[y - 13 + 8 = 4x - 8 + 8\]

OpenStudy (michele_laino):

and after a simplification, I write this: \[y - 5 = 4x\]

OpenStudy (michele_laino):

therefore, I subtract y from both sides: \[y - y - 5 = 4x - y\] please simplify

OpenStudy (anonymous):

y=4x+5

OpenStudy (michele_laino):

I got this: \[4x - y = - 5\]

OpenStudy (anonymous):

thats the final answer?

OpenStudy (michele_laino):

yes!

OpenStudy (anonymous):

y=1?

OpenStudy (michele_laino):

as we can see, from my equation above, the missing coefficients, are: for x ---> \(4\) for y ---> \(-1\) for coefficient at the right side ---> \(-5\)
