Question

0,4(x-3) =0, 5(4+x) -2, 5)

Answer 1

Ответ:

х=7

Пошаговое объяснение:

0,4(х-3)=0,5(4+х)-2,5)

0,4х-1,2=2+0,5х-2,5

0,4х-1,2=0,5х-0,5

0,5х-0,4х=1,2-0,5

0,1х=0,7

х=7

Answer 2

Let's solve the equation step by step:

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

First, distribute the constants on the right side of the equation:

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

Now, simplify both sides of the equation:

0.4x - 1.2 = 2 + 0.5x - 2.5

Next, let's isolate the variables on one side of the equation and the constants on the other side. To do this, we can subtract 0.5x from both sides and add 1.2 to both sides:

0.4x - 0.5x = 2 - 2.5 + 1.2

Now, simplify the equation further:

-0.1x = -0.3 + 1.2

Combine the constants on the right side:

-0.1x = 0.9

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

x = 0.9 / (-0.1)

x = -9

So, the solution to the equation is x = -9.
