Question

0,5(x+4)-2,5=0,4(3+x)​

Answer 1

Ответ:

х=17

Пошаговое объяснение:

0,5х+2-2,5=1,2+0,4х

0,5х-0,5-1,2-0,4х=0

0,1х-1,7=0

0,1х=1,7

х=1,7:0,1

х=17

Answer 2

Ответ:

17

Пошаговое объяснение:

0,5*(х+4)-2,5=0,4*(3+х)

0,5х+2-2,5=1,2+0,4х

0,1х=1,7

х=17

Answer 3

To solve the equation $0.5(x+4) - 2.5 = 0.4(3+x)$, follow these steps:

Step 1: Distribute the constants and variables within the parentheses. $0.5x + 2 - 2.5 = 0.4x + 1.2$

Step 2: Combine like terms on both sides of the equation. $0.5x - 0.5 = 0.4x + 1.2$

Step 3: Subtract $0.4x$ from both sides of the equation to isolate the $x$ terms. $0.1x - 0.5 = 1.2$

Step 4: Add $0.5$ to both sides of the equation to further isolate the $x$ terms. $0.1x = 1.7$

Step 5: Divide both sides by $0.1$ to solve for $x$. $x = \frac{1.7}{0.1} = 17$

So, the solution to the equation is $x = 17$.
