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