A=9x since it is 9 times B.
B=x since we do not know what B is we give it a variable for its value call it for sake of argument x.
9x+x=50,000,000 since they said the total value of the payment of A and B combined is 50,000,000.
10x=50,000,000 by combining like terms.
10x/10=50,000,000/10 by the division property of equality.
x=5,000,000 by simplifying and using the multiplicative inverse property.
9 (5,000,000)=45,000,000 since they are asking for the paid value of A.
