Question

any body solve
x+y=5
4x+6y=8​

Answer 1

Answer:

x=11

y= -6

Explanation::

Given:

x+y=5 (1)

4x+6y=8 (2)

Solution:

By elimination method:

x+y=5 (1)×4

4x+6y=8 (2)

4x+4y=20 (3)Subtracting eq(4) from eq(3)

4x+6y=8 (4)

(-) (-) (-)

-2y=12

$y = \frac{ - 12}{2}$

y= -6

Substituting y= -6 in eq(1)

x+y=5

x-6=5

x=6+5

x=11

Let's verfify by substituting x=11 and y= -6 in eq(2) as eq(1) is verified

4x+6y=8

4(11)+6(-6)=8

44-36=8

8=8

Since,LHS=RHS

Hence,

The given solution:

x=11

y= -6

Answer 2

x+y=5. (1)

4xt6y=8. ( 2)

equation 1 multiply by 4

then. 4xt4y=20. ( 3)

x=11 and y= -6
