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 a + 3a = 2a + 6z + 3 for a in terms of z.
| \(\frac{1}{14}\)z - \(\frac{4}{7}\) | |
| -z + 5 | |
| -3z - 3 | |
| -2z - 1\(\frac{2}{3}\) |
