Question

A) x+0,56+x=11,2 б) x-6,786=8,5

Answer 1

1)2x=11+0,56
2x=11,56
x=11,56:2
х=5,78

Answer 2

Let's solve the equations step by step:

a) x + 0.56 + x = 11.2

Combining like terms: 2x + 0.56 = 11.2

Subtracting 0.56 from both sides: 2x = 11.2 - 0.56 2x = 10.64

Dividing both sides by 2: x = 10.64 / 2 x = 5.32

Therefore, the solution to the equation is x = 5.32.

b) x - 6.786 = 8.5

Adding 6.786 to both sides: x = 8.5 + 6.786 x = 15.286

Therefore, the solution to the equation is x = 15.286.
