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 2b - 7b = -8b + 8y + 1 for b in terms of y.
| -1\(\frac{2}{3}\)y + 2\(\frac{1}{3}\) | |
| -2y + 2 | |
| \(\frac{3}{5}\)y + \(\frac{2}{5}\) | |
| 1\(\frac{1}{2}\)y + \(\frac{1}{10}\) |
