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 -3b - 5b = 9b + 8z + 5 for b in terms of z.
| 2\(\frac{1}{3}\)z - \(\frac{2}{3}\) | |
| \(\frac{3}{10}\)z + \(\frac{1}{5}\) | |
| z + 7 | |
| -1\(\frac{1}{12}\)z - \(\frac{5}{12}\) |
