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 -8a + 3a = 8a + 4z + 7 for a in terms of z.
| -\(\frac{1}{16}\)z - \(\frac{7}{16}\) | |
| z - 1\(\frac{1}{4}\) | |
| \(\frac{8}{15}\)z + \(\frac{1}{5}\) | |
| -4\(\frac{1}{3}\)z + 3 |
