Question

Solve the equation-(NOT-using graphical method) 4×-5y+16=0
2×+y-6=0

Answer 1

Answer:

I hope it will help you try to follow me so that I can help you in next example

4x-5y=-16.....1

2x+y = 6.......2

multiple equation 2by 5

we get...

10x+5y =30.....3

add equation 1and3

4x-5y=-16

+10x+5y =30

-----------------

14x=14

x=1

put in equation 2

2x+y=6

2+y=6

y=4

Answer 2

Answer:

(x,y)=(1,4)

Step-by-step explanation:

1st step

4x - 5y = -16

2x + y = 6

2nd step

4x - 5y = - 16

-4x -2y = -12

(eliminate one variable by adding the equations)

3rd step

-7y = -28

4th step

y = 4

5th step

2x + 4 = 6 (solve)

x = 1
