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