Answer:

x = 10 + 2.5y    y = -4 - 0.4x

Step-by-step explanation

Subtract 2x from both sides.

-5y = 20 + 2x

Divide by -5 on both sides.

y = -4 - 2/5x     or you can do   y = -4 - 0.4x

and then to find x, add 5y to both sides of original equation.

2x - 5y = 20

2x = 20 + 5y

Divide by 2 on both sides.

x = 10 + 2.5y

Answer:

Step-by-step explanation:

2x-5y=20

Making y the subject

-5y = -2x + 20

Dividing by -5

y = -2/-5x + 20/-5

y = 2/5x - 4

So comparing with y = mx + c

Slope m = 2/5

Intercept c = -4
