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