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 + 5b = b + 8y - 8 for b in terms of y.
| -1\(\frac{5}{8}\)y + 1\(\frac{1}{8}\) | |
| -\(\frac{5}{16}\)y + \(\frac{7}{16}\) | |
| 3y - 8 | |
| 1\(\frac{1}{6}\)y + \(\frac{5}{12}\) |
