Question

) Solve the pair of equations : 6x + 5y = 5
2x – 27 = 11y

Answer 1

Answer:

X=5/2

y=-2

Step-by-step explanation:

let 6x+5y=5..….…........1

2x-11y=27......….......2

multiply the equation 2 with 3

3(2x-11y=27). =6x-33y=81.............4

subtract equation 1 and 3

=(6x+5y=5)-(6x-33y=81)

=6x+5y-6x+33y=5-81

=5y+33y=-76

=38y=-76

=y=-76/38

=y=-2

substitute y value in equation 1

6x+5y=5

6x+5×(-2)=5

6x-10=5

6x=5+10

6x=15

x=15/6

x=5/2
