Question

solve the following pair of linear equations x/10+y/5+1=15 and x/8+y/6=15​

Answer 1

Answer:

x=120

y=10

Step-by-step explanation:

x/10+y/5+1=15

x/10+y/5=15-1

(x+2y)/10=14

x+2y=140

x=140-2y

x/8+y/6=15

(3x+4y)/24=15

3x+4y=360

Taking the value of x from the first equation

3(140-2y)=360

420-6y=360

420-360=6y

60=6y

y=10

Now,subsituting the value of y in equation 1

x=140-2(10)

x=140-20

x=120
