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 -5b + 5b = -2b - 7z + 7 for b in terms of z.
| -\(\frac{5}{8}\)z + \(\frac{7}{8}\) | |
| \(\frac{11}{12}\)z - \(\frac{1}{4}\) | |
| 4z - 2\(\frac{1}{3}\) | |
| -2z - 1\(\frac{1}{3}\) |
