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 - 9b = b + 7z + 7 for b in terms of z.
| \(\frac{12}{13}\)z + \(\frac{6}{13}\) | |
| z + \(\frac{5}{6}\) | |
| -8z - 3\(\frac{1}{2}\) | |
| 1\(\frac{2}{3}\)z - 2\(\frac{1}{3}\) |
