Step-by-step explanation:
if the two integers are x and y
xy=-10
x+y=-9
x+(-10/x)=-9
x2+9x-10=0
(x-1)(x+10)=0
x=1 or x=-10
if x=1, y=-10
if x=-10, y=1
so the two integers are 1 and -10

Answer:
x = 6
Step-by-step explanation:
Given
3x - 17 + 2x = 13 ← simplify left side
5x - 17 = 13 ( add 17 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
