Wittaler [7]3 years ago

You solve for X in one equation and plug it into the other. So... 

<span>5x+6Y=13 </span>
<span>5x=13-6Y </span>
<span>x=(13-6Y)/5 </span>

<span>Then, you replace X in the other equation... </span>

<span>-5x+2y=11 </span>
<span>-5[(13-6y)/5]+2y=11 </span>
<span>-13+6y+2y=11 </span>
<span>8y=11+13 </span>
<span>8y=24 </span>
<span>y=3 </span>

<span>Now that you have Y, you just solve for x using either equations... </span>

<span>5x+6(3)=13 </span>
<span>5x=13-18 </span>
<span>5x=-5 </span>
<span>x=-1 </span>

<span>Therefore, X = -1 & Y = 3

</span>

Why might working on a commission basis make dealing with finances more difficult
Kobotan [32]
<span>Dealing with finances becomes more difficult when working on a commission basis because unlike working on a salary basis, there is no regular pay. A commission means that earnings are based on rate of sale or number of completed tasks. Income may be reduced if you do not sell enough, or fail to complete enough tasks.</span>

Consider a convex hexagon in which all pairs of opposite sides are parallel. Prove that if one pair of opposite sides have equal
hjlf

A pair of the opposite sides of a hexagon has equal length and this is proved below.

<h3>How to illustrate the hexagon?</h3>

It should be noted that a hexagon is a polygon that has six sides.

In this case, it has 6 sides.

The total angles will be:

= (n - 2) × 180

= (6 - 2) × 180

= 720°

Each angle will hence be:

= 720°/6

= 120°

Each angle are equal and this illustrates that the parallel sides are equal.

A diagram is attached to illustrate the pair of parallel sides.
