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 b + 8b = -9b + 6z + 4 for b in terms of z.
| -1\(\frac{3}{10}\)z - \(\frac{1}{5}\) | |
| -2z + 9 | |
| \(\frac{5}{6}\)z - \(\frac{5}{6}\) | |
| -\(\frac{1}{5}\)z + \(\frac{2}{5}\) |
