Question

2. solve 4x+6/y=15 and 6x-8/y=14​

Answer 1

Answer:

Hey!!

Step-by-step explanation:

Given pair of linear equations,

4x+6/y=15....................................1

6x-8/y=15.....................................2

By eq1 we get,

4x=15-6/y

4x=(15y-6)/y

x=(15y-6)/4y.................................3

Substituting eq3 in eq2 we get,

6{(15y-6)/4y}-8y=15

(90y-36)/4y-8y=15

(90y-36-32y)/4y=15

90y-36-32y=60y

2y=-36

y=-18

Substituting value of y in eq3 we get,

x=(-270-6)/-72

x=-276/-72

x=23/6

Hence solution of given pair of linear equation=(23/6,-18)
