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 - z + 1 for b in terms of z.
| -\(\frac{1}{5}\)z - \(\frac{7}{15}\) | |
| -6z + 2\(\frac{1}{2}\) | |
| -\(\frac{1}{7}\)z - \(\frac{1}{7}\) | |
| -1\(\frac{4}{9}\)z - \(\frac{1}{3}\) |
