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 - 6b = 3b + 7z - 8 for b in terms of z.
| z + 1\(\frac{2}{5}\) | |
| -\(\frac{8}{11}\)z - \(\frac{9}{11}\) | |
| 13z - 8 | |
| z + 3 |
