Question

9. a) 8(9 – 2x) = 5(2 – 3x);B)2(x – 3) = 3(2x - 1);​

Answer 1

Ответ:

а)72 - 16х = 10 - 15х

-х = -62

х = 62

б)2х - 6 = 6х - 3

2х - 6х = -3 + 6

-4х = 3

х = - 3 / 4

Answer 2

Ответ:

Пошаговое объяснение:

8(9 – 2x) = 5(2 – 3x)

72-16x=10-15x

16x-15x=72-10

x=62

Ответ: 62.

2(x – 3) = 3(2x - 1)

2x-6=6x-3

6x-2x=3-6

x=-3/4

Ответ: -3/4.

Answer 3

a) To solve the equation 8(9 - 2x) = 5(2 - 3x), we can start by simplifying both sides of the equation:

8(9 - 2x) = 5(2 - 3x) 72 - 16x = 10 - 15x

Next, we want to isolate the variable x on one side of the equation. Let's move all the terms containing x to the left side:

-16x + 15x = 10 - 72 -x = -62

To solve for x, we can multiply both sides of the equation by -1 to eliminate the negative sign:

x = 62

So the solution to the equation is x = 62.

b) To solve the equation 2(x - 3) = 3(2x - 1), let's simplify both sides:

2(x - 3) = 3(2x - 1) 2x - 6 = 6x - 3

Next, let's move all the terms containing x to the left side:

2x - 6x = -3 + 6 -4x = 3

To solve for x, we divide both sides of the equation by -4:

x = 3 / -4 x = -3/4

So the solution to the equation is x = -3/4.
