Given:
Selling price of a machine = 7000/-
Gross loss = 20%.
To find:
The cost and gross loss.
Solution:
Let x be the cost of machine.
According to the question,
Divide both sides by 0.8.
So, the cost of the machine is 8750/-.
Now,
Therefore, the gross loss is 1750/-.
If x= mass of 1 load of sticks and y= mass of 1 load of bricks and a load of bricks is twice as heavy as a load of sticks y = 2x then,
4x + 4y = 771 ; 4x + 4(2x) = 771 ; 12x = 771 ; x= 64.25 kg
To find y: y = 2x = 2*64.25 = 128.5 kg
Total weight of 1 load of bricks and 3 loads of sticks: y + 3x
128.5 + 3*64.25 = 321.25 kg

We are given the following two equations
Let us subtract the second equation from the first equation.
Therefore, the result of subtracting the second equation from the first is
2$ + x * 6 = How much money they spent.
Distributive property- 6( x + 2)
