Answer:
Step-by-step explanation:
x + 3 y = 1 ----------------(I)
-3x - 3y = -15 -------------(II)
Add the equations and y will be eliminated and we can find the value of x
(I) x + 3y = 1
(II) <u>-3x -3y = - 15</u> {Now add}
-2x = - 14
x = -14/-2
x = 7
Plugin x =7 in equation (I)
7 + 3y = 1
3y = 1 - 7
3y = -6
y = -6/3
y = -2
Answer:
Neither
Step-by-step explanation:
−1.3x−(−8.9x) = −1.3x + 8.9x = 7.6x
−1.3x+(−8.9x) = −1.3x −8.9x = -10.2x
Answer: Neither
The answer would be,
14.79

<h3>
<u>Step-by-step explanation:</u></h3>
Given that , a retailer makes a profit of 5% by selling a fan for Rs 735 . So let us take CP be x .
Now , here
Here we assumed CP to be x , and profit % is 5% . So , its SP will be

<u>Hence</u><u> the</u><u> </u><u>CP</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>fan</u><u> </u><u> </u><u>was</u><u> </u><u>Rs</u><u> </u><u>7</u><u>0</u><u>0</u><u> </u><u>.</u></h3>
The value of b would be 47
