------------------------------------------------------------------------ Find the value of y ------------------------------------------------------------------------ y - 18 = 14 + 18 + 18
y = 32 ------------------------------------------------------------------------ substitute y = 32 into 2 (y + 9) ------------------------------------------------------------------------
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.
