1. What would be the first step in solving the equation below for r ? A = 4r
a add 4 to both sides
b subtract 4 to both sides
c divide 4 to both sides
d multiply 4 to both sides

C; multiply 4 to both sides

Step-by-step explanation:

When you want to solve for a variable, you always want to isolate it.

So, to move 4, we have divide:

= .

The 4 in 4r is "one'd" out, and now we have 1r, or simply r.

Now, we have r = A/4

stops on an even number.
