5.6h -6.8+6.8=43.27+6.8
5.6h=50.07
now divide both sides by 5.6
\[\frac{ 5.6h }{ 5.6 }=\frac{ 50.07 }{ 5.6 }=8.94\]
h=8.94 :)

ghazi is that distributive property now? or is it just normal ?
ghazi
Best Response

1
its just normal, you dont need to use distributive here , it is used only when there is something like this 5(x+3) = 5*x+5*3

post a question where you are supposed to use distributive law, you cant use distributive here, how could you when there is nothing to distribute

is something funny?
ghazi
Best Response
You've already chosen the best response.
1
now you have to go this way
1.4*u - 1.4*3.7 =17.08
ghazi
Best Response
You've already chosen the best response.
1
you need to multiply 1.4 with the stuff inside bracket that is, you have to distribute 1.4 over u and 3.7
ghazi
Best Response
You've already chosen the best response.
1
then it will be 1.4u-5.18 = 17.08 after that add 5.18 both sides, clear?
LonelyandForgotten
Best Response
You've already chosen the best response.
1
so you add 5.18 to 17.08?
ghazi
Best Response

1
what ,
its simple, look this is what you have to do to distribute 1.4|dw:1363044693962:dw|

yes add 5.8 to 17.08, correct
ghazi
Best Response

1
sorry you are right
ghazi
Best Response

1
now you have 1.4u=22.26 divide each side by 1.4 , actually you have to take everything away from variable that is 'U' here
ghazi
Best Response
You've already chosen the best response.
1
\[\frac{ 1.4 u }{ 1.4 }=\frac{ 22.26 }{ 1.4 }\]

is this your question , 13d-53=9d+19 ?
ghazi
Best Response
You've already chosen the best response.
1
if yes then
13d-53=9d+19 subtract 9d both the sides
13d-9d-53=9d-9d+19
4d-53=19
now add 53 on both sides
4d-53+53=19+53
4d=72
divide both sides by 4
d=18 that is correct
