Question

0.8(7-0.5x)-0.2(28+4x)=0

Answer 1

0,8(7-0,5х)-0,2(28+4х)=0

5,6-0,4х-5,6-0,8х=0

-0,4х-0,8х=0

-0,12х=0

х=0

Answer 2

Ответ:

5.6-0.4х-5.6-0.8х=0

-1.2х=0

х=0

Answer 3

Let's solve the equation step by step:

0.8(7 - 0.5x) - 0.2(28 + 4x) = 0

Distribute the multiplication:

5.6 - 0.4x - 5.6 - 0.8x = 0

Combine like terms:

-1.2x = 0

Divide both sides by -1.2:

x = 0 / -1.2

Simplifying:

x = 0

Therefore, the solution to the equation is x = 0.
