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