The answer is D) you could multiply A by -4 and B by 5,
This choice would help you cancel out the x variable so that you could solve for the y. To see this, multiply the x terms by the given amounts.
Equation A (just the x)
5x ----> multiply by the -4 above
5x * -4 = -20x
Equation B (just the x)
4x -----> multiply by the 5 above
4x * 5 = 20x
Since -20x and 20x cancel when adding, these are the numbers that you are looking for.
This is a working backwards problem. You know he has $35 at the end. Before he gave his brother $5, he would have $40, which is half of what he had before he bought the clothes, so he would have had $80. Before he spent the $40 on shoes, he would have had $120, so the answer is $120.
If y=kxy=kxy, equals, k, x, where kkk is a constant, and y=24y=24y, equals, 24 when x=6x=6x, equals, 6, what is the value of yyy

The right answer for the question that is being asked and shown above is that: "(Choice C)C. 202020." If y=kxy=kxy, equals, k, x, where kkk is a constant, and y=24y=24y, equals, 24 when x=6x=6x, equals, 6, the value of yyy when x=5x=5x, equals, 5 is 202020.
