Math Question Help?


#1

Hey fellows i want to solve the below question, both of them are wrong , the real answer is 6 , value of y. ( I want to know what is the mistake in those alternate methods, that i am no able to get 6 answer. Please)

The real solution is

Its very frustating. WTF ?


#2

(y / 2) - 5 = 1

(y / 2) - 5 + 5 = 1 + 5 (add 5 on both sides)

(y / 2) = 6

y = 2 x 6 (multiply when moving to RHS)

In your second attempt, you have to multiple all parts of the equation by 2 instead of just multiplying by 2 on the RHS. See here:

(y / 2) - 5 = 1

[(y / 2) x 2] - (5 x 2) = 1 x 2 (multiply all by 2)

y - 10 = 2

y = 10 + 2 = 12

yep same here

in our books it was under the topic of basic algebra

the basic solution is that if u do somethin on one side of the equal to u have to balance it on the other

eg u multiply one side by 2 u have to do it on the other side 2
