You need to work out the three simultaneous equations from the question and then solve them. R=(1/3)(B+G) B=(7/20)(B+R+G) => B=(7/13)(R+G) G=R+9. G-9=(1/3)((7/13)(G-9+G)+G) => 2G-27=(7/13)(2G-9) => 26G-351=14G-63 => 12G=288 => G=24 R=G-9=24-9=15 B=(7/13)(R+G)=(7/13)(15+24)=(7/13)*39=21. Now its easy to answer your questions: a) Total pens = 60, R=15. So fraction of red is 15/60=1/4 b) Total pens = 60. Hope that helps :-)

enable s start up by using multiplying the extensive type "7" into the paranthesis to the left (7 x 3 and seven x b). that provides us here: 2b - (21 + 7b) = b + 3 we are actually going to eliminate the paranthesis, and could no longer ignore to alter each and all the indications interior of it! "-" turns into "+", and "+" turns into "-". this provides us here: 2b - 21 - 7b = b + 3 o.k., our next project is to circulate each and all the numbers to the left, and each and all the unknown numbers with variables to the suited. do this by using subtracting 3 from -21 and upload 7b to b, and then additionally subtract 2b from (b + 7b). that provides us: -24 = 6b b = -24 / 6 b = -4.
