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 + 9b = -7b - 8z + 1 for b in terms of z.
| -\(\frac{1}{8}\)z - \(\frac{9}{16}\) | |
| \(\frac{4}{7}\)z + 1\(\frac{2}{7}\) | |
| -1\(\frac{5}{12}\)z + \(\frac{1}{12}\) | |
| -5z + 2\(\frac{1}{2}\) |
