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