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 - 3b = 8b + 4z + 4 for b in terms of z.
| -\(\frac{7}{13}\)z - \(\frac{4}{13}\) | |
| -\(\frac{1}{7}\)z + \(\frac{1}{7}\) | |
| 3z + 6 | |
| 5z + 3\(\frac{1}{2}\) |
