Please can anyone help me solve this math problem it's for my sister and she's submitting it tomorrow I've tried every method I know but I couldn't get the answer it's a number to words question
1) 2 is added to twice a certain number and the sum is doubled. The result is 10 less than 5 times the original number. Find the original number
2) I add 12 to a number and then double their sum. The result is one and a half times what I get when I double the original number and add 12. find the number
There where 3 questions but I managed to solve one using simultaneous equations but these ones are complicated
Mods please help me push this to the front page.. Thanks

Call on your ancestors they might be of help alot

Drop recharge card...
1) 2(2 + 2x) = 5x - 10
2) 2(12 + y) = 3/2(2y + 12)

Turn it to equation, then solve simultaneously.

guy you're asking at the wrong time like this Na I'm really blessed

I tried it but it didn't work

doesn't require you to solve simultaneously

Turn each into equations It's been done already Above

The number is x
1) 2(2 + 2X)= 5X-10
4+4X=5X-10
X= 14 show full step ooo...so she doesnt lose marks

2) (12+X) double the sum 2(12+X)
2(12+X)= (2X +12)3/2
2(24+2X)= 3 (2X +12)
48+4X=6X+36
6X-4X=48-36
X=12/2
X=6

thanks man but how did you get 14 in the number 1 questions I will really appreciate it if you explain even a bit

4+4X=5X-10
4+10=5X-4X
14=1X
X=14/1
X=14

Collect like terms one side each

4+4X=5X-10
4+10=5X-4X
14=1X
X=14/1
X=14

thanks man
