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 -3a + 2a = 4a - z - 3 for a in terms of z.
| -\(\frac{3}{11}\)z + \(\frac{3}{11}\) | |
| \(\frac{3}{7}\)z + \(\frac{3}{7}\) | |
| -z - \(\frac{2}{15}\) | |
| -\(\frac{2}{7}\)z + \(\frac{1}{7}\) |
