anonymous 2 years ago If you were to solve the following system by substitution, what would be the best variable to solve for an
d from what equation? 2x+6y=9 3x-12y=15 A.y, in the second equation B.x, in the first equation C.y, in the first equation D.x, in the second equation Calculus1
I'm sorry that I'm not in calculus, but hopefully I can help. Personally, I would choose: D.) x; in the second equation ; because it has easier numbers to figure out, you'll get it eventually...
We know that in 3 weeks you get $15 now you can divide 3 by 15 to get $5 per week so since we know how much you earn per week you multiply $5 by 5 weeks to get $25
