I don't how to find the inverse equation:

y= 2x +5
y= -2x+ 3
y= -4x + 3
y= 4x + 7

I assume that your question is asking how to solve x.

x = ( y - 5 ) / 2

x = ( y - 3 ) / -2

x = ( y - 3 ) / -4

x = ( y - 7 ) / 4

The general formula is
y = kx +c ≡ x = ( y - c ) / k

I think what you want to do is to solve the given equation for the other variable

y = 2x + 5
y - 5 = 2x
(y - 5)/2 = x

x = (y - 5)/2

Or do you mean x =

Take the first one:
y = 2x + 5

Subtract 5 from each side
y - 5 = 2x + 5 - 5
y - 5 = 2x

Divide each side by 2

(y - 5 ) / 2 = (2x) / 2
(1/2)y - (5/2) = x

x = (1/2) y - (5/2)

to find the inverse of these equations simply solve for x:

x = (y-5)/2

x = (3-Y)/2

x= (3 - y)/4

x = (y-7)/4

You mean -y?
-y = -2x -5

y= -0.5x+5
y=0.5x+3
y=0.25+3
y=+0.25x+7
