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 -2a + 4a = 5a + 4y + 1 for a in terms of y.
| y - \(\frac{1}{7}\) | |
| -\(\frac{1}{5}\)y + \(\frac{1}{5}\) | |
| -\(\frac{5}{6}\)y - \(\frac{1}{3}\) | |
| -\(\frac{5}{7}\)y + \(\frac{3}{7}\) |
