Seeing as you posted the same question twice I will answer twice.
There would be 93 oranges
10perbag-7= no of oranges
9perbag+3= no of oranges
For no of oranges to be the same for both equations there would be 93
10 oranges per bag + 7 additonal
9 oranges per bag + 3 needed
solving the equations would give 93 oranges.
1 brick = 1 kg + 1/2 brick
So 1 brick must way 2kg.
I knew the answer just hoping someone foolishly said 10cents.
2*22-(-3)=11
A minimum of -14 will occur at x=1
