Question

1)|7x-2|=02)|5х-4|=03)|10х-1|=0

Answer 1

1. |7х-2|=0
7х-2=0
7х=2
х= 2/7
2. |5х-4|=0
5х-4=0
5х=4
х= 0,8
3. |10х-1|=0
10х-1=0
10х=1
х= 0,1

Answer 2

1)2/7;-2/7
2)4/5;-4/5
3)1/10;-1/10

Answer 3

1. |7x-2| = 0 When the absolute value of a quantity equals zero, that means the quantity itself is zero. Therefore: 7x-2 = 0 7x = 2 x = 2/7

So the solution to the equation is x = 2/7.

2. |5x-4| = 0 Again, when the absolute value of a quantity equals zero, that means the quantity itself is zero. Therefore: 5x-4 = 0 5x = 4 x = 4/5

So the solution to the equation is x = 4/5.

3. |10x-1| = 0 Once again, when the absolute value of a quantity equals zero, that means the quantity itself is zero. Therefore: 10x-1 = 0 10x = 1 x = 1/10

So the solution to the equation is x = 1/10.
