Given:

Profit made in previous financial year = $10 million

We need to write an equation to find the profit made by the business.

Solution:

Let the profit (in millions) made by  business B be 'y'.

Now given:

business B making 4 times as much profit as business A.

so we can say that;

Now we know that;

Profit made in previous financial year is equal to sum of profit (in millions) made by  business A and profit (in millions) made by  business B.

framing in equation form we get;

Substituting the value of y in above equation we get;

Hence The equation to find the profit made by business combined is .

On Solving above equation we get;

profit (in millions) made by  business A =

profit (in millions) made by  business B =

Hence Business A made $2 million profit and Business B made $8 million profit.
