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 = 4b + z - 5 for b in terms of z.
| -1\(\frac{1}{12}\)z - \(\frac{7}{12}\) | |
| z - \(\frac{7}{8}\) | |
| 2z + 2\(\frac{1}{2}\) | |
| -\(\frac{7}{11}\)z + \(\frac{1}{11}\) |
