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