How many solutions does 3x-5y=8; 5x-3y=2 have

Can someone with this one pre-calc question? the finishing time for a runner completing the 200-meter dash is affected by the tail-wind speed, s. the change, t, in a runner's performance is modeled by the function shown below: t= 0.0119s^2 - 0.308s - 0.0003 predict the change in a runner's finishing time with a wind speed of 3 meters/second. note: a negative answer means the runner finishes with a lower time. round to the nearest hundredth.

Write each fraction as an equivalent fraction with a denominator of 120then write the original fractions in order from samllest to largest

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
