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 -2b - 4b = 2b - 2y + 1 for b in terms of y.
| -\(\frac{1}{2}\)y - \(\frac{1}{4}\) | |
| -13y - 3 | |
| -\(\frac{3}{10}\)y + \(\frac{7}{10}\) | |
| \(\frac{6}{7}\)y + \(\frac{1}{7}\) |
