Solve the system of equations. −5y+8x=−185y+2x=58\begin{aligned} & -5y+8x = -18 &5y+2x = 58 \end{aligned}−5y+8x=−185y+2x=58 x=x=x=x, equals y=y=y=y, equals

Step-by-step explanation:

These are simultaneous equations. The coefficients of y in both equations are the same, other than the difference in signs. We can thus eliminate y by adding both equations (if they had the same sign, we would have needed to subtract one equation from the other).

Substitute for x in any of the equations. We are using the first one here.
