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 = -b - 2z + 3 for b in terms of z.
| 5z - 9 | |
| z - \(\frac{4}{9}\) | |
| -\(\frac{7}{10}\)z + \(\frac{9}{10}\) | |
| -\(\frac{3}{7}\)z + \(\frac{3}{7}\) |
