First, let's combine like terms:

$2x-x+7 = x+3+4$

$x+7=x+7$

Subtract 7 from both sides:

$x = x$

Because x = x, it means that this expression has infinite solutions. The solution set for this is (-∞ < x < ∞).

If the clothing maker bought 500 m2 of this fabric, how much money did he lose? Use 1tepiz=0.625dollar and 0.9144m=1yard.

Ivanshal [37]

1 yard^2 = 0.8361m^2.?

<span>The solution to the problem is as follows:

So he spent (.625 x 400) = $250.00 per m^2. </span>
He paid out (500 x 250) = $125,000 on the deal.
He received (500 / 0.8361) = 598.014592 yard^2 of fabric.
That would have cost (598.014592 x 120) = $71,761.75 locally.
He lost (125,000 - 71,761.75) = $53,238.25 on the deal.

<span>You can rework with the incorrect conversion factor.

I hope my answer has come to your help. God bless and have a nice day ahead!
