0.375 times 8 minus 7x equals 0.2, find x equals

0.375 times 8 minus 7x equals 0.2, find x equals

0.375 times 8 minus 7x equals 0.2
3-7X=0.2
7X=3-0.2
7X=2.8
X=2.8÷7
X=0.4

3. 12 out of 5 times (4 out of 15 plus 2 out of 5) minus 24 out of 5, (1 out of 5 minus 2 out of 25) times 75 5, 7x divided by 1 out of 3 equals 5 out of 6

(3)
12 out of 5 times (4 out of 15 plus 2 out of 5) minus 2 out of 5
=12 out of 5 times (4 out of 15 plus 6 out of 15) minus 2 out of 5
=12 out of 5 times (10 out of 15) minus 2 out of 5
=12 out of 5 times (2 out of 3) minus 2 out of 5
=8 out of 5 minus 2 out of 5
=6 out of 5
(4)
(1 / 5 minus 2 / 25) times 75
=(5 / 25 minus 2 / 25) times 75
=3 out of 25 times 75
=3x3
=9
(5)
7x divided by 1 / 3 is 5 / 6
Seven times three is five sixths
21x = 5 / 6
X = 5 / 126

4-5 times (x minus 6) equals 5-7x plus 6
The title is a and B two warehouses, a is B's 5-7. If from B transfer 6 tons to a, then a is B's 4-5?

If a is 5 tons, B is 7 tons
(5x+6)\(7x-6)=4\5
5(5x+6)=4(7x-6)
3x=54
x=18
So a has 90 tons and B 126 tons
