Answer 2

THE ANSWER IS A follow

this question is a two answer.....

1.

5T+2C=990.....eq(1),

5T+2C=990.....eq(1),T-C=30,

5T+2C=990.....eq(1),T-C=30,then

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),7T=(990+60),

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),7T=(990+60),7T=1050,

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),7T=(990+60),7T=1050,T=150,

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),7T=(990+60),7T=1050,T=150,then

5T+2C=990.....eq(1),T-C=30,then2T-2C=60........eq(2),7T=(990+60),7T=1050,T=150,thenC=150- 30=120
