Answer:
I guess the application method by hands is more harmful. As pesticides are some sort of chemical substances which are used to kill insects and other sort of pests in any kind of plant. And we also know that pesticides are chemical substances.So when pesticides are typically applied by hands it can damage your palm skin.After applying pesticides you wash your hands.

Then, you will fall sick as well as your family members. So, isn't it harmful to apply pesticides by using your hands??
Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
