Let's make it a simple equation, yes? We'll use the variable <em>x</em> Equation involving multiplication: 2x=10 We'll solve it to make sure it works. Since the solution has to be five, we'll plug that in for <em>x</em> 2×5=10 10=10 This works, so we can move on. Equation involving division: 10÷x=2 Again, we'll solve it to make sure it works, plugging in 5 for <u /><em>x</em> 10÷5=2 2=2 This equation works as well. The two equations are 2x=10 and 10÷x=2
