If f(x)=-3x+4 and g(x)=2 solve for the value of x for which f(x)=g(x) is true

Hey there!

To start, because you know that f(x) is equal to -3x+4 and g(x) is equal to 2 and they are both equal to each other, you can write your equation as this:
-3x+4=2
(f(x)) (g(x))

Now, solve for x:
-3x+4=2
-3x=-2
x=2/3

Therefore, x is 2/3.

First you set the two equations up to equal each other: -3x+4=2
Subtract the 4 to the other side to get
-3x = -2
Lastly divide both sides by -3 to get x= 2/3
Hope this helped!! :)
