Question

one equation of a pair of dependent linear equation is 5x+7y=2 the second equation can be :
a. 10x+14y+4=0
b. -10x-14y+4=0
c. -10x+14y+4=0
d. 10x-14y=-0​

Answer 1

Answer:

a. 10x+14y-4=0

Hope it may help u

Answer 2

5x+7y=2

x+y+5+7=2

x+y+12=2

x+y=12-2

x+y=10

a.10x+14y+4=0

=10x+14y=0-4

=10x+14y=-4

=x+y+10+14=-4

=x+y+24=-4

=x+y=-4-24

=x+y=28

b.10x-14y+4=0

same a sum but change the symbols please you try the answer.

c.-10x+14y+4=0

=-10x+14y=0-4

=-10x+14y=-4

=x+y-10+14=-4

=x+y+4=-4

=x+y=-4-4

=x+y=8

d.10x-14y=0

=x-y+10-14=0

=x-y-4=0

=x-y=-4

Thank you
