Write an equation that involves
multiplication, contains a variable, and
has a solution of 5. Then write another
equation that has the same solution and
includes the same variable and numbers
but uses division.

We can use any equation, as long as it’s solution is 5.

So, 4x(5+x)-2(5x+2x^2)=50

10x=50

x=5

Now, to use division:

20x/10+ 4x^2/4x^2=11

Simplifying we get:

2x+1=11

2x=10
x=5.

This is a little complicated, but I hope this helps!
