Question

5x - 4y =-3
Y = -3x + 5
Solve for x and y

How do we solve for x and y when the formats of the equations are different. That's we here I'm lost. When I try to get the answer I get confused

Answer 1

so the formats are different. So what? Rearrange them so they are the same!

5x - 4y = -3
3x + y = 5

Now you can manipulate them.

Or, since you know that y = -3x+5, use that in the other equation:

5x - 4(-3x+5) = -3
Solve for x, and then get y.

Answer 2

So would it be
5(1) -4y (-3(1)+5)= -3
Y=1 ??
