i need help with these kinds of equations HELP PLS!!?

Question

i never seem to get these correct:
42-7y=-3y-6

it seems sooo easy but i can't get the right answer. can someone explain it to me? ty

Answer 1

42 - 7y + 3y = - 6
-7y + 3y = - 6 - 42
- 4y = - 48
4y = 48
y = 12

Answer 2

Solve for the "y" variable.... 42-7y = -3y-6

First: combine terms with the same variable - add 3y to both sides (when you move a term to the opposite side, always use the opposite sign).

42-7y+3y = -3y+3y-6
42-7y+3y = - 6
42 - 4y = - 6

SEc: subtract 42 from both sides...

42 - 42 - 4y = - 6 - 42
- 4y = - 6 - 42
- 4y = - 48

Third: solve for "y" by isolating it - divide both sides by -4.

- 4y/-4 = - 48/-4
y = - 48/-4
y = 12

Answer 3

If you get all the "y" terms on one side and all the constant (number) terms on the other, you should be okay.

42-7y=-3y-6
adding 3y to both sides
42-4y=6
subtract 42 from both sides
-4y=-36
y=9

check your work
42-7(9) should equal 3(9)-6
42-63=21 and 27-6 equals 21 so answer is correct

Answer 4

42-7y=-3y-6
42=4y-6
48=4y
12=y

Plugging this in for y gives -42 on both sides, so it checks.

Answer 5

42-7y = -3y-6

add 7y to both sides
42 = 4y - 6

add 6 to both sides
48 = 4y

divide both sides by 4
y = 48/4
y = 12

Answer 6

42 - 7y = - 3y - 6

+ 6

48 - 7y = - 3y

+ 7y

48 = 4y

/4

y = 12

Answer 7

hey ty. move -3y to the left. so its +3y.
42 to the other side so its -42.
3y-7y=-6-42
-4y=-48
4y=48
y=48/4=12

Answer 8

42-7y=-3y-6
42+6 = 7y-3y
48 = 4y
y = 12

Answer 9

add 7y to both sides - you want to get all the y's on one side.
42 = 4y - 6
now add 6 to both sides
48 = 4y
now divide by 4 on both sides
12 = y

Answer 10

42 - 7y = -3y - 6 ... add 6 to both sides
48 - 7y = -3y ... add 7y to both sides
48 = 4y ...divide both sides by 4
12 = y
