Exercise 5
Which of the following options gives a correct value for one of the variables.
Solve the following systems:
Question 1:
(a) |
y = 1 |
(b) |
y = -2 |
(c) |
x = 2 |
(d) |
x = 3 |
(c) |
x = 2 |
|
|
Question 2:
(a) |
 |
(b) |
 |
(c) |
 |
(d) |
 |
(a) |
|
|
|
Question 3:
(a) |
 |
(b) |
 |
(c) |
0 | (d) |
There is no solution |
(d) |
There is no solution |
|
Dividing the second equation by 2 results in two similar terms on the left, but two different terms on the right. So there is no solution here. Lines are parallel and do not intersect. |
