The number that when multiplied by 3, then 4 is subtracted and 2 added and the answer is 16 would be 6 .
4(8+2x)=5x+1132+8x=5x+118x-5×=11-323x=-213 3=-7Therefore the number is -7
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
The sum is the total when numbers are added together, the product is the total when they are multiplied.
