Solve the equation for y -8x+4y=20

8x-5y=-20

Step-by-step explanation:

First you have to collect it like terms (5y-8x=20

Then reorder the terms (-8x+5y=20)

Next is to change the signs (8x-5y=-20)

Then you have your answer

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
