Question

5m-2n=-1, 10m-7n=10 find the value of m and n ​

Answer 1

Answer:

n=-4 &m=-9/5

Step-by-step explanation:

(5m-2n=-1 )*2------> 10m-4n=-2

10m -7n =10

difference of the equation 1 and 2 is,

10m-10m-4n-(-7n)=-2-10

3n=-12

n=-4

substitute n=-4 in equation 1

5m-2(-4)=-1

5m=-9

m=-9/5

Answer 2

Answer:

n= -4 and m= 9/5.

Step-by-step explanation:

multiply 1st equation with 2

and then sub it from 2nd
