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 -7a - 8a = 2a - 3y - 5 for a in terms of y.
| -\(\frac{5}{9}\)y + \(\frac{5}{9}\) | |
| y - \(\frac{3}{7}\) | |
| -\(\frac{13}{16}\)y + \(\frac{5}{16}\) | |
| -7y + 3 |
