Question

0,5(х+4)-2,5=0,4)(х+3)​

Answer 1

Ответ:

x=17

Пошаговое объяснение:

0,5(х+4)-2,5=0,4(х+3)​

0.5x+2-2.5=0.4x+1.2

0.5x-0.5=0.4x+1.2

0.5x-0.4x=1.2+0.5

0.1x=1.7

x=17

Answer 2

It appears there might be a typographical error in the equation you provided. Let's correct it and solve it:

The equation you've given is:

0.5(x + 4) - 2.5 = 0.4(x + 3)

First, distribute the constants (0.5 and 0.4) to the terms in the parentheses:

0.5x + 2 - 2.5 = 0.4x + 1.2

Now, let's simplify the equation by combining like terms. Subtract 2.5 from both sides of the equation:

0.5x - 0.3 = 0.4x + 1.2

Next, subtract 0.4x from both sides of the equation to isolate the x terms on one side:

0.5x - 0.4x - 0.3 = 1.2

Now, combine the x terms:

0.1x - 0.3 = 1.2

Add 0.3 to both sides to isolate the x term:

0.1x = 1.2 + 0.3

0.1x = 1.5

Now, to solve for x, divide both sides by 0.1:

x = 1.5 / 0.1

x = 15

So, the solution to the equation is x = 15.
