Question

how many solution does the pair of linear equation 2x + y =6 and 4x +2y = 12 have? pls answer ​

Answer 1

Answer:

These simultaneous equations have no solution.

Explanation:

If you multiply both sides of the first equation by  

2

then you get:

4

x

−

2

y

=

12

The second equation gives us:

4

x

−

2

y

=

−

3

SInce  

12

≠

−

3

these two equations cannot be satisfied simultaneously.

The graphs of these two equations are a pair of parallel lines and do not intersect:

graph{(4x-2y-12)(4x-2y+3) = 0 [-10, 10, -5, 5]}

Step-by-step explanation:

Answer 2

as they are equal

the lines are parallel to each other

parallel lines have no solution

so no. of solutions = 0
