Question

) 5m - 3n
= 19; m - 6n = -7​

Answer 1

Step-by-step explanation:

An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic and lipophilic. Oils have a high carbon and hydrogen content and are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.

Answer 2

Answer:

5m-3n=19 equation first

m-6n=-7 equation second

multiply equation II by 5

5m -30n =-35

now by eliminating method solve the both equations

5m-3n=19

5m-30n=-35

27n=54

n=2

now put the value of n in equation first

5m-3(2)=19

5m-6=19

5m=25

m=5

now we have the answer

n=2,m=5
