Question

5-9x 3+5x 5-3x _____- _____= ____ 8 4 2

Answer 1

Ответ:

х=-3

Пошаговое объяснение:

5-9x/8 - 3+5x/4 = 5-3x/2

Общий знаменатель - 8

(5-9х)-2*(3+5х)=4*(5-3х)

Раскроем скобки

5-9х-6-10х=20-12х

-1-19х=20-12х

Переносим неизвестные влево

-19х+12х=20+1

-7х=21

Ответ

х=-3

Answer 2

Let's solve the expression step by step:

1. Combine like terms on the left side of the equation: (5 - 9x) + (3 + 5x) - (5 - 3x)

2. Distribute the negative sign to both terms inside the parentheses: 5 - 9x + 3 + 5x - 5 + 3x

3. Combine the constants and the x terms: (5 + 3 - 5) + (-9x + 5x + 3x) (3) + (-x) 3 - x

Now, the equation becomes: 3 - x = 8 - 4 - 2

To solve for x, we can combine the constants on the right side of the equation:

3 - x = 2

Now, let's isolate x by bringing 3 to the other side of the equation:

-x = 2 - 3 -x = -1

To solve for x, we need to multiply both sides by -1 (to get rid of the negative sign):

x = -1

So the value of x that satisfies the equation is -1.
