Simplifying
6r + 7 = 13 + 7r
Reorder the terms:
7 + 6r = 13 + 7r
Solving
7 + 6r = 13 + 7r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-7r' to each side of the equation.
7 + 6r + -7r = 13 + 7r + -7r
Combine like terms: 6r + -7r = -1r
7 + -1r = 13 + 7r + -7r
Combine like terms: 7r + -7r = 0
7 + -1r = 13 + 0
7 + -1r = 13
Add '-7' to each side of the equation.
7 + -7 + -1r = 13 + -7
Combine like terms: 7 + -7 = 0
0 + -1r = 13 + -7
-1r = 13 + -7
Combine like terms: 13 + -7 = 6
-1r = 6
Divide each side by '-1'.
