Urgent please help me I need all the steps, I wil give the person full starts and 15 points for answering Solve the system by substitution
-4.5x-2y=-12.5
3.25x-y=-0.75

Need help very badly

x=-1.273

y=-3.387

Step-by-step explanation:

-4.5x-2y=12.5            (1)

6.50x-2y=-1.5            (2)  [Multiplied by 2]

Now, (2)-(1)⇒

11x=-14

x=-14/11=-1.273

Now,putting the value of x in 3.25(-1.273)-y=-.75

y=-3.387

Hope, this helps you.

f(x) = y

f(-3) = -5
