The answer to your question is
Step-by-step explanation:
Data
4x - 8y = -16 ------------ (I)
x - 2y = - 8 ------------ (II)
a) Solve equation II for x
x = 2y - 8
Substitute x in equation I
4(2y - 8) - 8y = -16
8y - 32 - 8y = -16
8y - 8y = 32 - 16
0 = 16 The system has no solution because y was
cancelled.
b) When a system of equations do not have solution means that the lines are parallels and different.
<u><em>Answer:</em></u>

<em><u>Explanation:</u></em>
We know that John's height is
meters
<u>We are given that:</u>
John is
meters shorter than Paul
<u>This means that:</u>
Paul's height = John's height + 
Paul's height =
meter
<u>We are given that:</u>
Paul is 0.25 meters taller than Andrew
<u>This means that:</u>
Andrew's height = Paul's height - 0.25
Andrew's height =
meters
