Answer:
Both expression equals 5 when substituting 2 for x, because the expressions are equivalent.
Step-by-step explanation:
Given the expressions:
(1/2)x + 4
x + 6 - (1/2)x - 2
Substituting 2 for x in the equation :
(1/2)x + 4
x = 5
(1/2)2 + 4
2/2 + 4
1 + 4
= 5
x + 6 - (1/2)x - 2
Substituting 2 for x
2 + 6 - (1/2)2 - 2
8 - 2/2 - 2
8 - 1 - 2
= 5

The answer is B. This is just the answer in a simplified form.
Answer:
15
Step-by-step explanation:
5 x 3=15
Let Peters age be x
Phil's age is 1/5x+7---------------------------(i)
Phil's age can also be calculated as
4(1/5x+7)=2x-2--------------------------------(ii)
So,
4/5x+28=2x-2
28+2=2x-4/5x
30=10/5x-4/5x
30=6/5x
x=30*
x=25
