We can use the substitution method to solve this problem.

The second equation is
\sf y=2x, so we can plug in 2x for 'y' in the first equation:


\sf 5x-2y=3


\sf 5x-2(2x)=3

Multiply:


\sf 5x-4x=3

Combine like terms:


\sf x=3

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:


\sf y=2x


\sf y=2(3)

Multiply:


\sf y=6

This is the y-value of our solution. So our entire solution is (3, 6).
