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 = 2b + 4z + 3 for b in terms of z.
| \(\frac{5}{6}\)z - \(\frac{1}{2}\) | |
| -4z + 4 | |
| -5z - 9 | |
| \(\frac{1}{2}\)z + \(\frac{5}{14}\) |
