How can I solve this using linear equations in two variables

Mr. Salonga has two investments. His total investment is Php 400,000. Annually, he receives 3% interest on one investment and 7% interest on the other. The total interest that Mr. Salonga receives in a year is Php 16,000.

a. How much money does Mr. Salonga have in each investment? b. In which investment did Mr. Salonga earn more? c. Suppose you were Mr. Salonga, in which investment will you place more money? Why?

if I'm using elimanation method, what numbers can i multiply to each equation?

Multiply each term in Equation 1 by -0.07 to eliminate y. The equation will become -0.07 x - 0.07y = -28,000. Combine the similar terms with Equation 2. The result will be -0.04x = -12,000. Then, -0.04x/-0.04 = -12,000/-0.04, the result is x = 300,000. Proceed to next step.

I think everything's there. Will be logging off :-)
