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 8b + 7b = 7b - 8x + 8 for b in terms of x.
| -1\(\frac{1}{2}\)x + 1\(\frac{3}{4}\) | |
| -15x + 8 | |
| x - \(\frac{1}{4}\) | |
| -\(\frac{2}{13}\)x - \(\frac{5}{13}\) |
