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