2x=10y +4 PLEASE HELP!!!!

Answer 1

What do you need to do with the system?

Answer 2

solve for x and y

Answer 3

Is the system\[\begin{matrix}-14 - 2 = y-7x \\ 2x = 10y + 4\end{matrix}\]

Answer 4

Do you have to use any particular method?

Answer 5

sorry.... it is:
-14=-20y-7x
10y +4 = 2x

Answer 10

First, we need to solve the first equation for x. We get\[x = -(20/7)y + 2\] Then we substitute this expression into the second equation. This yields \[10y - 2(-(20/7)y + 2) = -4\]Solve this for y and plug the value of y back into our expression for x.
Let me know what you get.

Answer 11

x=34
y=?
