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 + 6a = 8a - 5z + 5 for a in terms of z.
| z - \(\frac{5}{11}\) | |
| \(\frac{3}{10}\)z - \(\frac{9}{10}\) | |
| -4z + 2 | |
| \(\frac{5}{11}\)z - \(\frac{9}{11}\) |
