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