Question

5(0,5+2x)-5(1,1-x)=15x-3​

Answer 1

Ответ:

x∈∅

Объяснение:

5(0,5+2x)-5(1,1-x)=15x-3​

2,5+10х-5,5+5х=15х-3

3+15х=15х-3

3 ≠ -3 ⇒ x∈∅

Answer 2

To solve the equation, let's break it down step by step:

Given equation: 5(0,5+2x) - 5(1,1-x) = 15x - 3

First, simplify the expressions within the parentheses: 5(0,5+2x) = 5(0.5 + 2x) = 2.5 + 10x 5(1,1-x) = 5(1 - x) = 5 - 5x

Substituting these simplified expressions back into the equation: 2.5 + 10x - (5 - 5x) = 15x - 3

Next, distribute the negative sign to the terms inside the parentheses: 2.5 + 10x - 5 + 5x = 15x - 3

Combine like terms on both sides of the equation: 15x + 10x - 5x = 2.5 - 5 + 3

Simplify further: 20x - 5x = 0.5

Combine like terms again: 15x = 0.5

Finally, solve for x by dividing both sides of the equation by 15: x = 0.5 / 15 x = 0.0333 (rounded to four decimal places)

Therefore, the solution to the equation is x = 0.0333.
