How do you solve y= -3+3

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
