Question

2,4(3x+2)+0,3(x+4)=6,6решите пж

Answer 1

$2.4(3x + 2) + 0.3(x + 4) = 6.6 \\ 7.2x + 4.8 + 0.3x + 1.2 = 6.6 \\ 7.5x + 4.8 + 1.2 = 6.6 \\ 7.5x + 6 = 6.6 \\ 7.5x = 6.6 - 6 \\ 7.5x = 0.6 \div (7.5) \\ x = 0.08$

Answer 2

To solve the equation, we need to find the value of 'x' that satisfies the equation. Let's go step by step:

1. Distribute the numbers outside the parentheses to the terms inside: 2 * (3x + 2) + 0.3 * (x + 4) = 6.6

2. Perform the multiplication: 6x + 4 + 0.3x + 1.2 = 6.6

3. Combine like terms: 6x + 0.3x + 4 + 1.2 = 6.6

4. Combine the constants: 6.3x + 5.2 = 6.6

5. Now, isolate the term with 'x' on one side by moving the constants to the other side: 6.3x = 6.6 - 5.2

6. Subtract the constants on the right side: 6.3x = 1.4

7. Finally, solve for 'x' by dividing both sides by 6.3: x = 1.4 / 6.3

Now, calculate the value of 'x': x ≈ 0.22222

So, the solution to the equation is approximately x = 0.22222.
