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 + 10a = 3a - 9z + 1 for a in terms of z.
| -1\(\frac{3}{10}\)z + \(\frac{7}{10}\) | |
| 19z - 1 | |
| -z - 3 | |
| -\(\frac{5}{6}\)z + \(\frac{1}{2}\) |
