Question

Math 6. Grade 6.

Can anyone help me solve these equations? Soon as possible!
r - 5 1/6 = 10

What does r = ?


if x + 9 = 14, what is the value of 8(x - 2)?

What does x = ?

Answer 1

r - 5 1/6 = 10

r - 31/6 = 10
  + 31/6    +31/6

r = 91/6

So, r = 91/6.


And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.

8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
    +7    +7
8x = 21
x = 21/8

So, the answer is 21/8


HOPE THID HELPS AND I REALLY HOPE THAT THE SECOND ANSWER IS RIGHT!!!!!!
