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 = 2b + 8z - 6 for b in terms of z.
| 2\(\frac{3}{5}\)z - 1\(\frac{1}{5}\) | |
| -13z - 7 | |
| 6z + 2 | |
| 1\(\frac{1}{6}\)z + 1 |
