incorrect. What is the correct solution? What is the error?
-5(3-1) = 30
- 15-5r = 30
51 = 45
r =
-9
The solution is 9. (Type the value of r.)
What is the error?
O A. The right side of the equation should be 15 after subtracting – 15 from each side.
O B. The right side of the equation should be 9 after dividing each side by - 5.
O C . The left side of the equation should be -r after dividing each side by -5.
OD. The left side of the equation should be - 15+5r after distributing.
