Answer and Step-by-step explanation:
<u>To solve for r,</u>
You must take all the values away from r to the other side of the equal sign. We do this using our operations: Addition, Subtraction, Multiplication, and Division.
First, we see that -3.54 isn't connected to r directly, so we can add that to both sides of the equation to get rid of -3.54 on the left side of the equation.
2.5(r - 4.4) + -3.54 + 3.54 = 6.46 + 3.54
2.5(r - 4.4) = 10
Next, we see that 2.5 is multiplying the expression (r - 4.4). We would need to divide <u>both</u> sides of the equation by 2.5.

r - 4.4 = 4
Finally, we must add 4.4 from both sides to get r by itself.
r - 4.4 + 4.4 = 4 + 4.4
r = 8.4
<u>The answer is </u><u>8.4</u>
