Equation 1 is 5x - 2y - 4z = 3

and

Equation 2 is 3x + 3y + 2z = -3.

Eliminate z by copying Equation 1, multiplying Equation 2 by 2, and then adding the equations.

Consider the the equations:

Equation 1 is 5x - 2y - 4z = 3

and

Equation 2 is 3x + 3y + 2z = -3.

Eliminate z by copying Equation 1, multiplying Equation 2 by 2, and then adding the equations.

Equation 1 is 5x - 2y - 4z = 3

and

Equation 2 is 3x + 3y + 2z = -3.

Step 1: Given,

The equations 5x−2y−4z=3 and 3x+3y+2z=−3. We have to eliminate z from equation 1 and 2.

Step 2: Calculation

5x-2y-4z=3...(1)

3x+3y+2z=-3...(2)

Mult.(2)by 2, add(1)+(2),we get

5x-2y-4z=3

6x+6y+4z=-6

We get the equation

$\Rightarrow 11x+4y=-3$

A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 mabove the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian).

a) with what speed do the entwined foes start to slide acrossthe floor?

b) if the coefficient of kinetic friction of their bodies withthe floor is 0.250, how far do they slide?
