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 -b - 6b = -9b + 7z + 1 for b in terms of z.
| 1\(\frac{5}{8}\)z + \(\frac{1}{8}\) | |
| -1\(\frac{1}{4}\)z + 1 | |
| -5z - 5 | |
| -12z + 5 |
