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 + 7b = -2b - 4z - 9 for b in terms of z.
| 3z - 2\(\frac{1}{4}\) | |
| -11z - 9 | |
| -z - 2 | |
| \(\frac{1}{3}\)z + 1\(\frac{1}{3}\) |
