Solve the following system of equations: \begin{align*} 3x-5y&=-1.5,\\ 7x+2y&=4.7. \end{align*}Express your answer as an ordered pair $(x,y)$ of decimals.

(x, y) = (0.5, 0.6)

multiply the first one by 2

multiply the second one by 5

add them together

sove for x

sub x value back into either equation to solve for y
