HELP! Can someone please explain to me how to solve this question?
Sunny_sXe [5.5K]

Answer:

(-3.1, -32.5)

Step-by-step explanation:

Set the equations equal to each other: 25x+45=15x+14

Solve for x: 10x = -31

Solve for x: x=-3.1

Plug the x value back into one of the equations to find the value of y:

y = 15 (-3.1) +14

y = -32.5
