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 -8b + 2b = -3b - z + 9 for b in terms of z.
| 2\(\frac{2}{7}\)z - \(\frac{6}{7}\) | |
| -4z - 9 | |
| 5z - 1 | |
| \(\frac{3}{5}\)z - 1\(\frac{4}{5}\) |
