Question

If g(x) = 3(x − 2), find the value of x if g(x) = 6

Answer 1

6-2 = 4
4(3) = 12?

Answer 2

not quite, you are given g(x)=6, and you are also given g(x)=3(x-2) so you just need to equate the two to get:
6 = 3(x-2)
and solve from there.

Answer 3

you need to find x.

Answer 4

How do I find x?

Answer 5

ok, you start with:
6 = 3(x-2)
divide both sides by 3 to get:
2 = (x-2) = x-2
add 2 to both sides to get:
2+2=x-2+2
4=x

so x=4 is the answer

you can check this by substituting x=4 into the equation for g(x)=3(x-2):
g(4)=3(4-2)=3*2=6

which matches what you were given at the start.

Answer 6

g(x)=3(x-2)
g(x)=6 for a particular value of x, we've to find that
6=3(x-2)
6=3x-6
12=3x
x=4 solution

Answer 7

Ohhh I gotcha. I was only supposed to solve for x not the actual equation, so that was my mistake lol

Answer 8

yes - at least you are learning - thats the main thing. :=)
