Answer:<span>x=<span><span><span><span><span>−10/</span>3 </span>y </span>+ <span>4z</span></span>+<span>40/<span>3</span></span></span></span>
If we are eliminating x, we would multiply the 2nd equation by -5
5x + 18y = 23
x + 3y = 2....multiply by -5
-----------------
5x + 18y = 23
-5x - 15y = - 10 (result of multiplying by -5)
----------------add
0 + 3y = 13.....bye-bye x :)
X is got to a specific number but im not sure yet
Answer:
10=16[ by cost]
Step-by-step explanation: the cost of 10 chairs is x.
the cost 16 chairs is also x. 10x = 16x
4x is loss.
Profit or Gain = Selling price – Cost price. Loss = Cost price – Selling price. Profit Percentage = [Profit/C.P.]×100. Percentage Loss = [Loss/C.P.]×100.
In simple way, we can say that sp- cp[ when it is a gain], cp -sp[ when it is a loss]. here it is a loss as well as a gain. so do both according to the formula
