Question

Given the functions f (x) 3x- 4 and g(x) = 4x+ 10, find the value of x for which f(x)=g(x)

Answer 1

if f(x)=g(x), then you would set them equal to each other.
3x-4=4x+10       Subtract 3x from both sides:
-4=x+10             Subtract 10 from both sides:
-14=x                 And now you have your answer.
