how do I set up this equation?

Question

Mr. Rodriguez invests half his money in land, a tenth in stocks, and a twentieth in bonds. He puts the remaining $35,000 in his savings account. What is the total amount of money that Mr. Rodriguez saves and invests?

Answer 1

(1/2)x + (1/10)x + (1/20)x + 35000 = x

Answer 2

m represents the starting aboutn

Mr. Rodriguez's investments are:

m/2 + m/10 + m/20

That is 

13m/20

That leaves 7m/20 for his savings account

7m/20 = 35000

 

Can you solve for m and answer
