Answer:
12x
Explanation:
3x − 10 + 2x + 3x + x + 20 + 2x + 10 + x − 20
= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20
Combine Like Terms
= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20
= (3x + 2x + 3x + x + 2x + x) + (-10 + 20 + 10 + −20)
= 12x

Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs
For the -5+5y=40 the answers is y=9
And for 4x+3y=24 is x=-3/4y +6
