Solve for z 6x + 10y + 2z =20
What is the value of z when x = -5 and y= 1
Z=

z= 20

Step-by-step explanation:

First, substitute the given variables into the equation.

6(-5)+10(1)+2z= 20

Now, multiply to simplify the equation.

-30+10+ 2z= 20

Now, do some simple math to simplify.

(-30+10)+2z= 20

-20+2z= 20

Then, add 20 to both sides of the equation.

-20+2z= 20

+20       +20

2z= 40

Finally, divide both sides by 2 to isolate the variable.

2z= 40

2     2

z= 20

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
