When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 7b + 2b = 6b + 5x + 5 for b in terms of x.
| 3x + 5 | |
| -3x + 3 | |
| -\(\frac{6}{7}\)x - \(\frac{1}{7}\) | |
| 2x + 1 |
