$5x-2x=16+5$
Learn how to solve equations linéaires à une variable problems step by step online. 5x-5=2x+16. Group the terms of the equation by moving the terms that have the variable x to the left side, and those that do not have it to the right side. Apply the formula: a+b=a+b, where a=16, b=5 and a+b=16+5. Combining like terms 5x and -2x. Apply the formula: ax=b\to \frac{ax}{a}=\frac{b}{a}, where a=3 and b=21.
