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 -7b + 5b = 6b + 3x + 3 for b in terms of x.
| 6x + 9 | |
| \(\frac{2}{13}\)x - \(\frac{3}{13}\) | |
| \(\frac{1}{7}\)x + \(\frac{4}{7}\) | |
| \(\frac{3}{10}\)x + \(\frac{9}{10}\) |
