ANSWER: 3/6

WORKING:
find a common denominator. the lowest common demominator for 5 and 6 is 30. to get from 6 to 30, you multiply by 5. whatever you do to the numerator, you do to the denominator, so you multiply 3 by 5 as well and get 15. 3/6 becomes 15/30

do the same with the other fraction. to get from 5 to 30 you ×5, so do 2×5 as well, which is 10. 2/5 = 10/30

15/30 > 10/30 so 3/6 > 2/5

A number doubled and has four added to it. The result is divided by three and then added to the product of the original number a

IrinaK [193]

X= a number

(2x+4)/3 + (x+2)= 20
Multiply everything by 3 to eliminate the fraction
(3/1)((2x+4)/3) + (3)(x+2)= (3)(20)
2x+4+3x+6= 60
5x+10=60
Subtract 10 from both sides
5x=50
divide both sides by 5
x=10

Check:
Substitute answer in original equation
(2x+4)/3 + (x+2)= 20
(2(10)+4)/3+(10+2)= 20
(20+4)/3+12= 20
24/3+12= 20
8+12= 20
20=20

Hope this helps! :)

Multiply by -3

2x-3x-12=-5

Collect like terms

-x-12=-5

Move constant to the right to change its sign

-x=-5+12

Add

-x=7

Change the signs
