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 + 4b = 2b - 8z - 3 for b in terms of z.
| -\(\frac{6}{13}\)z - \(\frac{8}{13}\) | |
| 13z - 5 | |
| 3z + \(\frac{3}{4}\) | |
| 3\(\frac{1}{3}\)z - 1\(\frac{2}{3}\) |
