The product of 3 and a number increased by 8, is -48

May 13th, 2015

Let the number be m,

3  x m = 3m,

3m increased by 8 =  3m + 8, which equals -48.

So the algebraic equation  will be 3m + 8 = - 48.

NB: m can be replaced by any letter.

Hope this helps. You can ask any question if you are not satisfied.

Any question?

So would the answer be 18.6?

Absollutely right:

3m + 8 = -48

3m = -48-8

3m = -56

3m = -56/3

m= 18.67, to the nearest 2 decimal places.
