Answer:

The solution of the linear system is:

[tex]x = 2[/tex] and [tex]y = -2[/tex]

Step-by-step explanation:

The following linear equation is solved as follows:

[tex]8\cdot x + y = 14[/tex]

[tex]3\cdot x + y = 4[/tex]

After some algebraic manipulation:

[tex]y = 14 - 8\cdot x[/tex]

[tex]y = 4 - 3\cdot x[/tex]

[tex]14 - 8\cdot x = 4 - 3\cdot x[/tex]

[tex]10 = 5\cdot x[/tex]

[tex]5\cdot x = 10[/tex]

[tex]x = 2[/tex]

And finally,

[tex]y = 4 - 3\cdot (2)[/tex]

[tex]y = -2[/tex]

The solution of the linear system is:

[tex]x = 2[/tex] and [tex]y = -2[/tex]

Answer:

x = 2 , y = - 2

Step-by-step explanation:

8x + y = 14 ......,.......1

3x + y = 4.................2

Use elimination method, we subtract equation 2 from 1, which yields;

5x + 0 = 10

: 5x = 10 : X = 2

Substituting X value in equation 1 we have

8(2) + y = 14

: 16 + y = 14

y = 14 - 16 = - 2

∴ x = 2 , y = - 2
