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 5b - 7b = 7b + 3z + 7 for b in terms of z.
| 1\(\frac{5}{6}\)z - 1 | |
| -5z - 3\(\frac{1}{2}\) | |
| -z - 1 | |
| -\(\frac{5}{16}\)z - \(\frac{7}{16}\) |
