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 - 6b = 6b - 8z + 9 for b in terms of z.
| z - 1\(\frac{1}{7}\) | |
| \(\frac{3}{11}\)z - \(\frac{6}{11}\) | |
| 2z - 3 | |
| \(\frac{2}{7}\)z - 1\(\frac{2}{7}\) |
