Solve for r.–7–7r=–10r+8r=
To solve for r, we need to combine like terms and isolate the variable r.
Given equation: -7 - 7r = -10r + 8r
First, combine the like terms on the right side of the equation:
-7 - 7r = -2r
Now, isolate the variable r by adding 7r to both sides:
-7 - 7r + 7r = -2r + 7r
-7 = 5r
Finally, divide by 5 to solve for r:
r = -7/5
Therefore, the solution for r is r = -7/5.
