Question

.Solve the pair of linear equations 3x + 15y -13 =0 and
2x-5y -7=0 and hence find the value of m forwhich=
y= mx - 3​

Answer 1

Answer:

3x+15y-13=0

2x-5y-7=0

Multiply 2nd equation by 3 and add to 1st equation, you will get 9x=34

x=34/9

put this value of x in any Two of the above equations and calculate the value of y

y=1/9

put these values of x and y in y=mx-3

1/9=m×(34/9)-3

m=28/34=14/17
