Simplifying
3r + 7 = 34
Reorder the terms:
7 + 3r = 34
Solving
7 + 3r = 34
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3r = 34 + -7
Combine like terms: 7 + -7 = 0
0 + 3r = 34 + -7
3r = 34 + -7
Combine like terms: 34 + -7 = 27
3r = 27
Divide each side by '3'.
r = 9
Simplifying
r = 9
