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 2b + 4b = 9b - z + 2 for b in terms of z.
| -\(\frac{5}{7}\)z + \(\frac{3}{14}\) | |
| \(\frac{5}{7}\)z - \(\frac{2}{7}\) | |
| -7\(\frac{1}{2}\)z + 3 | |
| -z + 4\(\frac{1}{2}\) |
