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 -5b + 6b = -b - 7z + 1 for b in terms of z.
| 2\(\frac{1}{4}\)z + 1\(\frac{1}{4}\) | |
| \(\frac{8}{15}\)z + \(\frac{7}{15}\) | |
| 3\(\frac{1}{4}\)z - \(\frac{1}{4}\) | |
| 2z + \(\frac{3}{4}\) |
