Question

Given f(x) =3x -1 and g(x) = 2x-3, which value of x does g(x)=f(2)

Answer 1

f(x) = 3x - 1

g(x) = 2x - 3

g(x) = f(2)

g(x) = 3.2 - 1

g(x) = 6 - 1

g(x) = 5

If g(x) = 5, then, 2x - 3 = 5

2x - 3 = 5

2x = 5 + 3

2x = 8

x = 8/2

x = 4

So,

f(2) = g(4)

Answer 2

x=4 because if f(2)=3x-1 that means that x=2 will replace x in the equation so 3(2)=6 6-1=5.Then both need to equal to 5 so you need to do the he reverse of equations 5+3=8 and 2x=8 and 8÷4=2. I know I didnt explained quite perfectly but I know x=4.
