Question

0,4(x – 3) + 2,5 = 0,5(4 + x)

Answer 1

Ответ:

x = -7

Пошаговое объяснение:

0,4(x – 3) + 2,5 = 0,5(4 + x)

0,4x-1,2+2,5=2+0,5x

0,4x-0,5x=2+1,2-2,5

-0,1x=0,7

x=-0,7/0,1=-7

Answer 2

To solve the equation 0.4(x – 3) + 2.5 = 0.5(4 + x) for 'x', follow these steps:

Step 1: Distribute the constants inside the parentheses: 0.4x - 1.2 + 2.5 = 0.5x + 2

Step 2: Combine like terms on both sides of the equation: 0.4x + 1.3 = 0.5x + 2

Step 3: Subtract 0.4x from both sides to isolate the 'x' terms on one side: 0.1x + 1.3 = 2

Step 4: Subtract 1.3 from both sides to isolate the 'x' term on one side: 0.1x = 0.7

Step 5: Divide both sides by 0.1 to solve for 'x': x = 7

So, the solution for the equation is x = 7.
