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 - 3b = 7b + 5y + 4 for b in terms of y.
| -2\(\frac{1}{4}\)y - \(\frac{3}{4}\) | |
| -\(\frac{11}{17}\)y - \(\frac{8}{17}\) | |
| -\(\frac{4}{7}\)y - \(\frac{2}{7}\) | |
| 9y - 8 |
