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 + b = 4b - 7z - 7 for b in terms of z.
| 16z + 5 | |
| \(\frac{4}{5}\)z + \(\frac{7}{10}\) | |
| z - 2\(\frac{2}{3}\) | |
| -2\(\frac{1}{6}\)z - 1\(\frac{1}{6}\) |
