Let the u known number = x
Five times the number added to negative eight would be written as:
5x + (-8) which simplifies tips 5x -8
That gets subtracted from triple the sum of eight times the number and 3. Sum is addition so that part of the equation would be 3(8x+3)
Final equation is : 3(8x+3) - 5x -8
This can then be simplified to :
3(8x+3) = 24x +9
To get: 24x +9 -5x-8
Combine like terms to get: 19x+1
