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