Answer:
Substitute y=x-2y=x−2 into y=-0.5x+4y=−0.5x+4.
x-2=-0.5x+4x−2=−0.5x+4
2 Solve for xx in x-2=-0.5x+4x−2=−0.5x+4.
x=4x=4
3 Substitute x=4x=4 into y=x-2y=x−2.
y=2y=2
4 Therefore,
\begin{aligned}&x=4\\&y=2\end{aligned}
x=4
y=2

<span><span>Equation:- 45+<span><span>5/6 </span>x</span></span>=50
</span>1) Simplify both sides of the equation. <span><span><span><span>5/6 </span>x </span>+ 45 </span>= 50
</span>2) Subtract 45 from both sides. <span><span><span><span><span>5/6 </span>x </span>+ 45 </span>− 45 </span>= <span>50−45 </span></span><span><span><span>5/6 </span>x</span>=5
</span>3) Multiply both sides by 6/5.<span><span><span>(<span>6/5</span>)</span>*<span>(<span><span>5/6 </span>x</span>)</span></span>=<span><span>(<span>6/5</span>)</span>*<span>(5)</span></span></span><span>x=6
SO, x=6.

The answer to your question is (1,9) :)
The solution for this problem is:
<span>Let time taken by Emily be x </span>
<span>
then Aileen take 2/3 of x = 2x/3 </span>
<span>
1 min work of Emily = 1/x</span>
<span>
1 min work of Aileen = 1/ 2x/3 => 3/2x</span>
<span>
1 min work of both = 1/45</span>
<span>
1/x + 3/2x = 1/45</span>
<span>
5/2x = 1/45</span>
<span>
1/x = 2/225</span>
<span>
Emily take 225/2 mins to complete the work, then Aileen</span>
<span>= 225/2*2/3</span>
<span>= 75 mins.</span>
