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 + 4a = -8a + 8x + 8 for a in terms of x.
| \(\frac{4}{15}\)x + \(\frac{8}{15}\) | |
| -15x + 8 | |
| 6x - 4 | |
| -4\(\frac{2}{3}\)x - 2\(\frac{2}{3}\) |
