Hi i have a 7th grade math problem. please explain how you got your answer because im totally lost. plz &thnx?

Question

2w+4(7+3w)= (negetive)14

Answer 1

2w+4(7+3w)= -14
2w+4(7)+4(3w)= -14
2w+28+12w= -14
14w= -42
w= -3

Answer 2

2w+4(7+3w)= -14
first distribure 4(7+3w) so 4 times 7 is 28 and 4 times 3w is 12w

2w+28+12w=-14

and like terms 2w+12w equals 14w

14w+28=-14
subtract 28 to both sides

14w=-42
now divide by 14 on both sides

and w=-3

Answer 3

The basic rules are:
1. Expand expressions in brackets
eg 4(7 + 3w) = 28 + 12w

2. Group terms together if they are alike
eg 2w + 28 + 12w >> 14w + 28

3. Any change you make to one side of the equation, make exactly the same to the other side
eg 14w + 28 = -14

a. subtract 28 from both sides
14w = -14 - 28 = -42

b. divide both sides by 14
w = -42 / 14 = -3

Just practice a few and you will get the hang of it.

Answer 4

2w+4(7+3w)=-14
First you need to distribute the 4 into the (7+3w)
2w+28+12w=-14
Next you subtract 28 from both sides including the -14
2w+12w=-42
Now add the 2w and the 12w
14w=-42
Divide by 14
w=-3

Answer 5

2w+4(7+3w)= (negetive)14
2w+28+12w= -14 (muliplied the 4 by both 7 and 3w)
14w+28= -14 (combined the w's)
14w= -42 (subtracted 28)
w= -3 (divide by 14)

Answer 6

2w + 4(7+3w) = -14

4(7 + 3w) = 4x7 + 4x(3w) = 28 + 12w

2w + 28 +12w = -14

2w + 12w + 28 - 28 = (-14) - 28

14w = -42

14w / 14 = -42 / 14

w = -3

Answer 7

sixty 9=2x+x; x is the cost of the game, whilst the joystick is two times the cost of the game. Simplified, the equation is 3x=sixty 9. keep in mind x is the cost of the game, so the cost of the joystick would be 2 circumstances x. i will pass away you to do the fixing. good success!

Answer 8

oh god what school do you go to im in 7th and well wow. :O
