Question

 if m=5 in equation 5m - 3n=19 then find n= ? *

​

Answer 1

Step-by-step explanation:

5m - 3n = 19 (m = 5)

so, 5 × 5 - 3n = 19

25 - 3n = 19

25 - 19 = 3n

6 = 3n

6/3 = n

n = 2

Answer 2

Answer:

If m=5

So 5m-3n=19

5(5)-3n=19

25-3n=19

3n=19-25

3n=6

n=6/3(6divided by 3)

n=2

After checking by putting value of m and n

5(5)-3(2)=19

25-6=19
