mathstudent55 · Answer

Since you have the first equation already solved for y, substitute y into the second equation and solve by substitution.

anonymous · Answer

I mean the second equation is 9x-3y=14
not 9x-3y=114

whpalmer4 · Answer

Do as @mathstudent55 suggested.

whpalmer4 · Answer

1st eq is $y=3x-4$
Wherever you see $y$ in the second eq, replace it with $(3x-4)$

anonymous · Answer

ok

whpalmer4 · Answer

That gives you an equation with only $x$ as a variable.  Solve it. Then use the first equation to get the value of $y$ from that.

anonymous · Answer

i know but im not sure how to do it im very new to it and im not the best at math to begin with

whpalmer4 · Answer

Just do the substitution I suggested, and tell me your result.  Then we can walk through solving the equation.
