Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17
Answer:
there is no question I'm sorry but I will take brainlyist
10 x 28 = 280.
17.50 / 1.75 = 10 gallons.
10 x 28 = 280.
280 + 280 = 560
560 miles.
