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 - 6b = -6b - 7z + 9 for b in terms of z.
| -\(\frac{9}{13}\)z + \(\frac{2}{13}\) | |
| 1\(\frac{2}{3}\)z + \(\frac{1}{3}\) | |
| -4z + 1 | |
| -\(\frac{1}{8}\)z + 1\(\frac{1}{8}\) |
