n*(9 - 2) = 2*7 = 7n
5 - 2n
2 x 4 - x = 7x
The way to write that is 2X+5
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
58 = 2 x 29
5 - 2n
18-(2/x)
7-2x
if 2 positive numbers are multiplied, then the product is positive. if 2 negative numbers are multiplied, the product is positive. if a positive and a negative number are multiplied, the product is negative.
The number 4 is a product of 2 x 2, for example.

The product of 6 and -2 is -12.
It is; 2*3 = 6
The way to write that is 2X+5
the number is 8 2 times 8 = 16 16 minus 5 = 11
