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 + 7b = 7b - 5z - 1 for b in terms of z.
| 1\(\frac{2}{3}\)z - 2 | |
| -\(\frac{2}{5}\)z - 1\(\frac{2}{5}\) | |
| 3z + \(\frac{3}{4}\) | |
| 1\(\frac{1}{11}\)z + \(\frac{1}{11}\) |
