Question

0,4 × (х-3) = 0,5 × (4+х)​

Answer 1

Ответ:

Как-то так..............

Answer 2

Ответ:

-32

Объяснение:

0.4×(x-3)=0.5×(4+x)

0.4x-1.2=2+0.5x

0.4x-1.2-2=0.5x

0.4×-3.2=0.5x

0.5×=0.4x-3.2

0.5x-0.4x=-3.2

0.1x=-3.2

x= -3.2

Answer 3

To solve the equation $0.4 \times (x-3) = 0.5 \times (4+x)$, we can follow these steps:

Step 1: Distribute the constants on the right side of the equation. $0.4x - 0.4 \times 3 = 0.5 \times 4 + 0.5x$

Step 2: Simplify both sides of the equation. $0.4x - 1.2 = 2 + 0.5x$

Step 3: Move the terms containing $x$ to one side of the equation and the constants to the other side. $0.4x - 0.5x = 2 + 1.2$

Simplified: $-0.1x = 3.2$

Step 4: Solve for $x$ by dividing both sides by -0.1. $x = \frac{3.2}{-0.1}$

$x = -32$

So, the solution to the equation is $x = -32$.
