Question

Solve the equation. Round to the nearest 10th if necessary 7R -7 = 2r +18.

1.r=-5
2.r=5
3.r=2.2
4.r=1.2

Answer 1

To solve the equation 7R - 7 = 2r + 18, we need to isolate the variable "r" on one side of the equation.

Rearranging the equation, we have:
7R - 2r = 25

To solve for "r," we need the values of R. However, since the equation only provides a relationship between the variables, we cannot find an exact value for "r."

Therefore, there is no option that accurately represents the value of "r."
