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 -5a + 2a = 6a - 5z - 3 for a in terms of z.
| \(\frac{7}{11}\)z + \(\frac{3}{11}\) | |
| -z - 3\(\frac{1}{2}\) | |
| -\(\frac{5}{6}\)z + 1 | |
| -1\(\frac{5}{8}\)z + \(\frac{1}{8}\) |
