#x = 79.89#

Explanation:

#79.904 = 40.510 + 0.4931x#

In this equation, we need to solve for #x#. We do this by putting #x# on one side of the equation and all the numbers on the other side.

To make #x# by itself, we must subtract #40.510# from both sides:
#39.394 = 0.4931x#

Now we need to divide both sides by #0.4931# to get the final answer:
#79.89 ~~ x# (the #~~# in this case means around because I rounded it to the hundreth's decimal place)

So...
#x = 79.89#
