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 8b + 8b = 7b + 8y - 7 for b in terms of y.
| -\(\frac{1}{5}\)y - \(\frac{1}{5}\) | |
| y - 7 | |
| -\(\frac{6}{7}\)y - \(\frac{6}{7}\) | |
| 1\(\frac{6}{7}\)y - \(\frac{2}{7}\) |
