Question

Given the functions

f(x)=125 + 15x and g(x)=12x+140, find the value of x for which f(x)=g(x).

X=

Please hurry :)

Answer 1

X = 5

Explanation:

So what the equation is saying is that f(x) = g(x) so these equations are equal

The equation will look like this

125 + 15x = 12x + 140

I first began with subtracting the 12x from the 15x which will give you 3x

125 + 3x = 140

now we subtract 125 to 140 and you'll get 15

140-125 = 15 now divide by 3 leaving the x solo

15/3 = 5 so x is 5

hope that helps
