What is 3x+5=-2x+5 please I need help

x = 0

Step-by-step explanation:

3x + 5 = 2x + 5    

x + 5 = 5                 Subtract 2x from both sides

x = 0                       Subtract 5 from both sides

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
