To solve: 9 + 2 + 42 × 5 − 1
=9+2+(42×5)-1
=9+2-1+(42×5)
=10+210
=220
To solve: (9 + 2) + 42 × (5 − 1)
=11+(42×4)
=179
One of the thing we should note is that multiplication always comes first, or we might get the wrong answer.
Hope it helps!

Consider, cost of one bag of cotton candy=x
cost of one souvenir cup = y
Now, 4x+2y=36 , 2x+y=18------(I)
7x+3y=59-------(ii)
in (I), y=18-2x, substitute it in (ii),
7x+3(18-2x)=59
7x+54-6x=59
x=5, substitute it in equation (I),
2(5)+y=18
y=8....ANS
