Question

5(4x + 7)-3(8x - 3) = 7x​

Answer 1

Ответ:

4

Объяснение:

20х+35-24х+9=7х

11х=44

х=4

Answer 2

Ответ:

х=4

Объяснение:

1. умножаем 5 на числа внутри 1 скобки

(4х*5+7*5) = (20х+35)

2. умножаем -3 на числа внутри 2 скобки

(8х*(-3) * -3*(-3)) = (-24х+9)

получаем такое уравнение:

20х+35-24х+9=7х

3. Числа с "х" в левую часть уравнения, без "х" в правую(при перемещении знаки меняются на противоположные)

20х-24х-7х=-35-9

-11х=-44

х= -44:(-11)

х=4

Answer 3

To solve the equation 5(4x + 7) - 3(8x - 3) = 7x, you'll need to simplify the equation and then solve for the value of x. Here are the steps to do that:

1. Distribute the constants (numbers outside the parentheses) to the terms inside the parentheses:

   20x + 35 - 24x + 9 = 7x

2. Combine like terms on both sides of the equation:

   (20x - 24x) + (35 + 9) = 7x

   -4x + 44 = 7x

3. Add 4x to both sides of the equation to isolate the x terms on one side:

   -4x + 44 + 4x = 7x + 4x

   44 = 11x

4. Now, divide both sides by 11 to solve for x:

   44 / 11 = 11x / 11

   4 = x

So, the solution to the equation is x = 4.
