Web1. Solving Equations An equation states that two quantities are equal. This means that the left hand and right hand sides of the equals sign are equivalent, they balance. The equation may contain an unknown quantity that we wish to find. In the equation, 5𝑥𝑥 + 10 = 20, the unknown quantity is 𝑥𝑥. This means that 5 multiplie d by ...
