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