Question

3+2(9-7х) = 6-4х с решением пж

Answer 1

Ответ:

1.5

Объяснение:

3+18-14x=6-4x

21-14x=6-4x

21-6=-4x+14x

15=10x

x=15/10

x=1.5

Answer 2

Ответ:

3 +18-14х=6-4х

4х-14х=-3+(-18)

-10х=-21

х=2,1

Answer 3

To solve the equation 3 + 2(9 - 7x) = 6 - 4x, follow these steps:

Step 1: Distribute the 2 on the left side of the equation: 3 + 2 * 9 - 2 * 7x = 6 - 4x

Step 2: Simplify the equation: 3 + 18 - 14x = 6 - 4x

Step 3: Combine the constants on each side: 21 - 14x = 6 - 4x

Step 4: Get all the terms with 'x' on one side of the equation by adding 4x to both sides: 21 - 14x + 4x = 6 - 4x + 4x

Step 5: Simplify the equation further: 21 - 10x = 6

Step 6: Isolate the variable 'x' by subtracting 21 from both sides: 21 - 21 - 10x = 6 - 21

Step 7: Simplify: -10x = -15

Step 8: Finally, solve for 'x' by dividing both sides by -10: x = (-15) / (-10)

Step 9: Simplify the fraction: x = 3/2

So, the solution to the equation is x = 3/2.
