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 6b + 3b = 5b - 2z + 2 for b in terms of z.
| -5z + 2 | |
| -\(\frac{8}{15}\)z + \(\frac{1}{5}\) | |
| -\(\frac{3}{14}\)z + \(\frac{2}{7}\) | |
| -\(\frac{4}{7}\)z - \(\frac{3}{7}\) |
