Question

7(3-4x)=6-2(3+4x)Решите​

Answer 1

Ответ:

7(3-4x)=6-2(3+4x)

21-28х=6-6-8х

-20х= -21

х= 1,05

Answer 2

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

Step 1: Distribute the terms on both sides of the equation. 7 * 3 - 7 * 4x = 6 - 2 * 3 - 2 * 4x

Step 2: Simplify both sides of the equation. 21 - 28x = 6 - 6 - 8x

Step 3: Combine like terms on both sides. 21 - 28x = -8x

Step 4: Isolate the variable term on one side of the equation. To do this, add 8x to both sides of the equation. 21 - 28x + 8x = -8x + 8x 21 - 20x = 0

Step 5: Now, isolate the x term on one side by subtracting 21 from both sides. 21 - 20x - 21 = 0 - 21 -20x = -21

Step 6: Finally, solve for x by dividing both sides by -20. x = -21 / -20

Step 7: Simplify the fraction (if possible). x = 21/20

So, the solution to the equation is x = 21/20 or x = 1.05.
