Question

(4+5x)-3 (2-x)=16x-0,4​

Answer 1

Ответ:-0,2

Пошаговое объяснение:

3(2-х)=6-3х

4+5х-(6-3х)=16х-0,4

4+5х-6+3х=16х-0,4

8х-2=16х-0,4

8х-16х=2-0,4

-8х=1,6

-х=1,6:8

-х=0,2

х=-0,2

Answer 2

To solve the equation (4+5x) - 3(2-x) = 16x - 0.4, follow these steps:

Step 1: Simplify both sides of the equation.

(4 + 5x) - 3(2 - x) = 16x - 0.4

First, distribute the -3 on the left side:

(4 + 5x) - (6 - 3x) = 16x - 0.4

Now, remove the parentheses:

4 + 5x - 6 + 3x = 16x - 0.4

Step 2: Combine like terms on both sides.

(5x + 3x) + (4 - 6) = 16x - 0.4

8x - 2 = 16x - 0.4

Step 3: Isolate the variable term (x) on one side of the equation.

To do this, move the 8x term to the right side by subtracting 8x from both sides:

8x - 8x - 2 = 16x - 8x - 0.4

-2 = 8x - 0.4

Next, move the constant term (-0.4) to the left side by adding 0.4 to both sides:

-2 + 0.4 = 8x - 0.4 + 0.4

-1.6 = 8x

Step 4: Solve for x.

To get the value of x, divide both sides by 8:

x = -1.6 / 8

x = -0.2

So, the solution to the equation is x = -0.2.
