Answer 3

4x + 5y = 8
8x + ?y = ?

coincident means it is the same line......so what would you have to multiply 4x by to equal 8x ??

Answer 4

this is confusing

Answer 5

4x times what = 8x ??......better yet, 4 x what = 8

Answer 6

2

Answer 7

yes...and if you multiply one term by 2, you have to multiply all the terms by 2
2(4x ) + 2(5y) = 2(8)
do the math and what do you get now ?

Answer 8

so its 2 and 16

Answer 9

no....
2(4x) + 2(5y) = 2(8)
8x + 10y = 16

now to check if they are the same line..
8x + 10y = 16 --- reduce by dividing by 2
4x + 5y = 8......you see how , when reduced, they are the same line

so your answer is : 8x + 10y = 16
