*This is on the assumption that we are finding x*
For this, you will be doing a proportion, and your equation will look like this: [tex] \frac{40}{x} =\frac{50}{30} [/tex]
Firstly, you will need to cross-multiply. Your equation will look like this: [tex] 1200=50x [/tex]
And all you need to do with this equation is divide 50 on each side, and your answer should be [tex] 24=x [/tex]
