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 2b + 6b = -4b + 8x + 7 for b in terms of x.
| -\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| -\(\frac{11}{16}\)x - \(\frac{1}{8}\) | |
| \(\frac{1}{3}\)x + 1\(\frac{1}{6}\) | |
| -2\(\frac{1}{7}\)x + \(\frac{2}{7}\) |
