Question

8(7-4х)+5(8х-1)=9+7(4х+1) ​

Answer 1

Ответ:

х=-1,75

Объяснение:

8(7-4х)+5(8х-1)=9+7(4х+1) ​

56-32х+40х-5=9+28х+77

51+8х=86+28х

8х-28х=86-51

-20х=35

х=35/(-20)

х=-1,75

Answer 2

To solve the equation 8(7-4x) + 5(8x-1) = 9 + 7(4x+1), we'll follow these steps:

Step 1: Distribute the multiplication to simplify the equation: 8 * 7 - 8 * 4x + 5 * 8x - 5 * 1 = 9 + 7 * 4x + 7 * 1

Step 2: Simplify both sides of the equation: 56 - 32x + 40x - 5 = 9 + 28x + 7

Step 3: Combine like terms on each side: 56 + 8x - 5 = 16 + 28x

Step 4: Simplify further: 8x + 51 = 28x + 16

Step 5: Rearrange the equation by isolating the variable terms on one side: 8x - 28x = 16 - 51

Step 6: Simplify and solve for x: -20x = -35 x = -35 / -20 x = 7/4 or 1.75

Therefore, the solution to the equation is x = 1.75.
