What is 2x+2y=8 in standard form

x+y=4

Step-by-step explanation:

2x+2y=8

By taking out 2 from 2x+2y as common terms, we get

2(x+y)=8

Now, by dividing both sides by 2, we get

2(x+y)/2=8)2

x+y=4

66 sweets

Step-by-step explanation:

Step one:

We are told that the ratio for sharing the sweet is 4:7

that is Jack takes 4 parts and Josh takes 7 paths

If Josh got 18 more

then Let the amount that Jack got be x

so that Josh got x+18

step two:

applying the part to part method, we can find the quantity each of them go

4/7= x/x+18

cross multiply

7x= 4x+72

collect like terms

7x-4x= 72

3x=72

divide both sides by 3

x= 72/3

x= 24

so  Jack got 24 sweets

and Josh got 24+18=42 sweets

in all the sweets = 66 sweets
