Question

4 x minus 5 Y + 16 is equal to zero what 2x + Y - 6 is equal to zero

Answer 1

Answer:

y=4; x=1

Step-by-step explanation:

4x-5y= -16 eqn1

2x+y=6 eqn 2

multiply eqn2 with 2

4x+2y=12

4x-5y= -16

(-)  (+)    (+)

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

       7y=28

         y= 28/7 = 4

sub y=4 in eqn 2

2x+4=6

2x=6-4

2x=2

x= 1
