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 4b + 9b = -3b - z - 1 for b in terms of z.
| -1\(\frac{3}{7}\)z - \(\frac{1}{7}\) | |
| -\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) | |
| 4z - 2 | |
| \(\frac{5}{16}\)z + \(\frac{3}{8}\) |
