Find a pair of numbers that is a member of both -1y-1x=3 and -6x-5y=24

Okay, so this is known as a system of equations.

Also, putting a 1 in front of a variable is unnecessary, as that is a given.

-y - x = 3

-6x - 5y = 24

In the first equation, add x to both sides.

-y = 3 + x

Multiply all terms by -1.

y = -3 - x

Now that we have a value of y we can plug it into the second equation to solve for x.

-6x - 5(-3 - x) = 24

Distributive property.

-6x + 15 + 5x = 24

Combine like terms.

-x + 15 = 24

Multiply all terms by -1.

x - 15 = -24

Add 15 to both sides.

x = -9

Now that we have a value for x, we can plug it into the first equation to solve for y.

y = -3 - (-9)

y = -3 + 9

y = 6

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
