Answer: x = 21
Step-by-step explanation: First, isolate the x term by
subtracting 5 from both sides of the equation.
We get 1/3x = 7.
Next, multiply both sides of the equation by
the reciprocal of 1/3 which is 3/1 to get x by itself.
On the left, 3/1(1/3) cancels and on the
right when we multiply 7(3/1), we get 21.
So we have x = 21.
