Answer:
The numbers are 18 and 10.
Step-by-step explanation:
Equation:
a + b = 28; and a = b + 8
Solution:
Step 1: Solving for b
a + b = 28
(b + 8) + b = 28
2b + 8 = 28
2b/2 + 8/2 = 28/2
b + 4 = 14
b + 4 + (-4) = 14 + (-4)
b = 10;
Step 2: Solving for a
a + 10 = 28
a + 10 + (-10) = 28 + (-10)
a = 18
Step 3: Checking by substituting
18 + 10 = 28
28 = 28 (TRUE)
