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
