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 -6b + 2b = -9b + 9z - 1 for b in terms of z.
| -\(\frac{1}{16}\)z - \(\frac{7}{16}\) | |
| 2\(\frac{1}{4}\)z + 2 | |
| 2\(\frac{1}{3}\)z - \(\frac{1}{3}\) | |
| 4z - 7 |
