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 -4b + 5b = 3b - 8z - 5 for b in terms of z.
| \(\frac{3}{4}\)z - \(\frac{3}{4}\) | |
| \(\frac{11}{13}\)z + \(\frac{9}{13}\) | |
| z + 9 | |
| 1\(\frac{6}{7}\)z + \(\frac{5}{7}\) |
