-0,8(6х-2)+1,6(4-х)=ПОМОГИТЕ СРОЧНО!!!НУЖНО ПОЛНОСТЬЮ ВСЕ РАСПИСАТЬ​

Answer 1

Раскроем скобки и приведём подобные слагаемые:

= -0,8 · 0,6х - 0,8 · (-2) + 1,6 · 4 + 1,6 · (-х) =

= -4,8х + 1,6 + 6,4 - 1,6х =

= (-4,8х - 1,6х) + (1,6 + 6,4) = -6,4х + 8 = 8 - 6,4х

Ответ: 8 - 6,4х.

Answer 2

To solve the equation -0.8(6x - 2) + 1.6(4 - x) = 0, let's break it down step by step:

Step 1: Distribute the terms

Distribute the terms inside the parentheses to simplify the equation:

-0.8 * 6x + 0.8 * 2 + 1.6 * 4 - 1.6 * x = 0

Simplifying further, we get:

-4.8x + 1.6 + 6.4 - 1.6x = 0

Step 2: Combine like terms

Combine the x terms and the constant terms separately:

(-4.8x - 1.6x) + (1.6 + 6.4) = 0

Simplifying further, we get:

-6.4x + 8 = 0
