So for this you start by figuring out all the numbers that add up to equal 12. (0,12)(1,11)(2,10)(3,9)(4,8)(5,7)(6,6) Then you put them into the equation 3l+2s=33 l=the larger number and s=the smaller number To save space I'm only going to do the numbers that are the answers. (3,9) 3(9)+2(3)=33 27+6=33 33=33 TADA
