Solve the following system of equations with the substitution method:

$\displaystyle{\left\lbrace\matrix{{y}&=&\frac{{2}}{{5}}{x}-{17}\\{y}&=&-\frac{{2}}{{3}}{x}+{15}}\right.}$

y=(2/5)x-17, y=-2/3 x+15

so (2/5)x-17=(-2/3)x+15

(2/5)x+(2/3)x=15+17

(6/15)x+(10/15)x=32

(16/15)x=32

x=32*(15/16)=30

Let me know if you have any problem, thank you.
