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 -9b + 3b = -8b - 6z + 8 for b in terms of z.
| 9z - 8 | |
| -1\(\frac{1}{3}\)z + 1\(\frac{1}{3}\) | |
| -4\(\frac{1}{2}\)z + 1 | |
| \(\frac{1}{5}\)z - \(\frac{1}{5}\) |
