Question

2.5x+3*(0.5x-1.8)=3.8​

Answer 1

Ответ:x=5,6

Пошаговое объяснение:2,5x+3•(0,5x-1,8)=3,8

2,5x-1,5-1,8=3,8

2,5x-1,5x=3,8+1,8

X=5,6

Answer 2

To solve the equation 2.5x + 3*(0.5x - 1.8) = 3.8, follow these steps:

Step 1: Distribute the 3 on the left side of the equation:

2.5x + 3 * 0.5x - 3 * 1.8 = 3.8

Step 2: Simplify the equation:

2.5x + 1.5x - 5.4 = 3.8

Step 3: Combine like terms:

4x - 5.4 = 3.8

Step 4: Isolate the variable term (4x) on one side by moving the constant term (-5.4) to the other side. To do this, add 5.4 to both sides of the equation:

4x - 5.4 + 5.4 = 3.8 + 5.4

Step 5: Simplify:

4x = 9.2

Step 6: Solve for x by dividing both sides by the coefficient of x (which is 4):

x = 9.2 / 4

Step 7: Calculate the result:

x = 2.3

So, the value of x that satisfies the equation is x = 2.3.
