Use substitution to solve the system of equations. y + x = 3
y = 1.5x + 1 Show your work.

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)

1) letter c.

2) 4 square root of 9

hope this
