Question

If y-18=14, what is the value of 2(y+9)?

Answer 1

------------------------------------------------------------------------
Find the value of y
------------------------------------------------------------------------
y  - 18  =  14
   + 18     + 18

y  =  32
------------------------------------------------------------------------
substitute y = 32 into 2 (y + 9) 
------------------------------------------------------------------------

2( y + 9 ) = 2 ( 32 + 9 )
2 (y + 9 ) = 2 (41)
2 ( y + 9 ) = 82

------------------------------------
Answer: 82
------------------------------------

Answer 2

82 is the answer. to find y, you would add 18 to both sides of the equation (y-18=14 --> y=18+14, so y=32. now, you plug in 32 to the other equation. 32+9=41, and 41*2 = 82.
