Question 172877
solve by the substitution method
9x-9y=0
3x=14=y



The second equation is not correct. Check it to see which of the equal signs is correct.


Solve the system by solving one equation for either x or y and then substituting that result into the other equation. Let's solve the first equation for x.

9x-9y=0
9x = 9y
x = y

In the second equation, since x = y substitute x for y and then solve that equation for x. Once you know x, substitute that value in either of the initial equations and calculate y.
