I am supposed to solve y + y/2 = 1
I multiplied both sides by 2 and i got:
y + y = 2
And then when I solved for y I got the wrong answer.
The answer is y= = 2/3
When they multiplied both sides by 2, they also multiplied the other y with 2.
I don't understand why they multiplied the y with 2 instead of the 2 just cancelling out. Please explain why, thank you

y=1

Step-by-step explanation:

y + y/2= 1 all it is, is 1+1/2=1

So you add 1+1 you get 2 then see how many times 2 goes into 2 which is 1 so y should equal 1

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
