Solve for y is answer
2x+3y=1470
minus 2x from both sides
3y=-2x+1470
divide both sides by 3
y=-2/3x+490
The answer to the equation will be 68 degrees because it is an alternate interior angle to 68 in b. So now you must subtract 28 from 68 which is 40 and divide that by 4 and that is how you solve for x. I hope this helps.
I assume that you are talking about 2 integers
one of the integers must be negative while the other is positive
we can list integer pairs that multiply to -20:
-20 1
20 -1
-10 2
10 -2
5 -4
-5 4
now the only pair that when you add them together equals -8 is -10 and 2, so
-10 and 2 add to -8 and multiply to -20
