X, y - the numbers
The numbers multiply to 100.

The numbers add up to -29.

Substitute -x-29 for y in the first equation:

The numbers are
-4 and
-25.
Answer: 6+4x=26, 4x=20
Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.
If you solve the equation, 2x+3=13 (subtract 3 from both sides)
2x=10 (divide both sides by 2)
x equals 5.
if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.
1/5 + 1/3·x > 1/2·x - 1/4
1/3·x - 1/2·x > - 1/4 - 1/5
2/6·x - 3/6·x > - 5/20 - 4/20
- 1/6·x > - 9/20
1/6·x < 9/20
x < 54/20
x < 27/10
x < 2.7
Get a common denominator first.
89/120 becomes 1157/1560
90/130 becomes 1080/1560
Subtract the two and you get 77/1560
