Given the equation 3x + 1 = 16, solve for x

Step-by-step explanation:

We have the following expression:

and we need to solve for , so the first thing we have to do (in order to leave the x alone on one side of the equation) is move the +1 to the left sife with the opposite sign (-1):

now we divide each side by 3, and we get:

the answer is

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

yes. we do proportions in probabilities.
