The Answer is 2x + Y - 6 =0
Let 2k represent the original even number (such that k is an integer)
then 2(k + 1) is the next consecutive even number.
4(2k) - 16 = 2(k + 1)
8k - 16 = 2k + 2
6k = 18
k = 3
since 2k represents the original number, then 2(3) = 6 is the oroginal number

Answer:
50%
Step-by-step explanation:
Actual value - estimated value
Actual value = 24 miles
Estimated value = 36 miles
Estimated value - Actual value
= 36 miles - 24 miles
= 12 miles
% error = change in value / actual value × 100
= 12/ 24 × 100
= 1/2 × 100
= 50%
% error = 50%
