Q.5
4x-5y+16-0
2x+y-6-0
Solve the equation- (NOT- using graphical method
4x-5y+16-0
2x+y-6-0​

Answer 1

Answer:

x = 1, y = 4

Step-by-step explanation:

by elimination method

4x - 5y + 16 = 0

2( 2x + y - 6 =0)

4x - 5y + 16 = 0

4x + 2y - 12 = 0

4x - 5y + 16 = 0

-4x - 2y + 12 = 0

-7y + 28 = 0

$y \: = \frac{28}{7}$

$y \: = 4$

insert this in eq (2),

2x + (4) -6 = 0

2x = 2

$x \: = \frac{2}{2}$

$x \: = 1$
