Question

(x-4):2+3x=5 Прошу помочь. Заранее, спасибо.

Answer 1

$\frac{x-4}{2} +3x=5|*2 \\ \\ \frac{2*(x-4)}{2} +3x*2=5*2 \\ x-4+6x=10 \\ x+6x=10+4 \\ 7x=14\\x=7$

Answer 2

Домножаем на 2
х-4 +6х =10
7х=14
х=2

Answer 3

Solving the Equation (x-4)/2 + 3x = 5

To solve the equation (x-4)/2 + 3x = 5, we can follow these steps:

1. Multiply Through by 2: To get rid of the fraction, we can multiply through by 2 to clear the fraction.

2. Simplify: After multiplying through by 2, we simplify the equation.

3. Isolate x: We then isolate the variable x to solve for its value.

Let's solve the equation step by step.

Step 1: Multiply Through by 2

We can start by multiplying every term in the equation by 2 to clear the fraction.

The equation becomes: 2 * (x-4)/2 + 2 * 3x = 2 * 5

Step 2: Simplify

Simplify the equation after multiplying through by 2.

The equation simplifies to: (x-4) + 6x = 10

Step 3: Isolate x

Now, we can combine like terms and isolate the variable x.

The equation becomes: x - 4 + 6x = 10 Simplify further: 7x - 4 = 10 Add 4 to both sides: 7x = 14 Finally, divide by 7: x = 2

So, the solution to the equation (x-4)/2 + 3x = 5 is x = 2.
