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 -8b - 8b = 8b + 5z + 4 for b in terms of z.
| 5z - \(\frac{2}{3}\) | |
| \(\frac{5}{6}\)z + \(\frac{1}{3}\) | |
| -2\(\frac{3}{4}\)z - 1 | |
| -\(\frac{13}{16}\)z - \(\frac{1}{4}\) |
