Answer:
The numbers are 6 and 14
Step-by-step explanation:
Let the two numbers be x and y
x-y = 8
x+y = 20
Add the two equations
x-y = 8
x+y = 20
-----------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Subtract the two equations
x-y = 8
-x-y = -20
-----------------
-2y = -12
Divide by -2
-2y/-2 = -12/-2
y = 6
The numbers are 6 and 14

Answer:
x = 5/6
Step-by-step explanation:
Cross multiply.
18(x - 2) = 3(-7)
Divide both sides by 3.
6(x - 2) = -7
Distribute the 6.
6x - 12 = -7
Add 12 to both sides.
6x = 5
Divide both sides by 6.
x = 5/6
Answer: x = 5/6
