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 - 5a = -2a - 8y + 3 for a in terms of y.
| y - 7 | |
| -\(\frac{3}{5}\)y + 1 | |
| -\(\frac{3}{4}\)y + \(\frac{3}{4}\) | |
| -\(\frac{7}{10}\)y - \(\frac{7}{10}\) |
