Answer: 1), 2) and 5) are equivalent.
Step-by-step explanation:
Since in first expression, 2+x=5 ⇒ x= 5-2= 3⇒x=3
In second expression, x+1=4⇒ x=4-1⇒x=3
In third expression, 9+x=6 ⇒ x=6-9⇒x= -3
in Fourth expression, x+(-4)=7 ⇒ x=7+4 ⇒ x=11
In fifth expression, -5+x=-2⇒ x=-2+5 ⇒x=3
Thus, 1) 2) and 5) expression are giving the same result.
Therefore they are equivalent to each other.
48/3= 16 (cups)
16+16= 32 (twice as many plates)
So it would be 16
