You can put this solution on YOUR website! Let one number be x, then the other number is x+5 add like terms subtract 125 from each side now we have to factor now you set each segment in parenthesis equal to zero and solve for x, so first segment is
2x+20=0 subtract 20 from each side, and you get
2x=-20 divide each side by 2 and you get
x=-10 now we do the other segment
x-5=0 add 5 to each side an dyou get
x=5
So the answers are x=-10 or x=5
