Question

0,2 * (X-2)=0,7*(X+3) РЕШИТЕ УРАВНЕНИЕ

Answer 1

Ответ:

0,2х-0,4=0,7х+2,1

0,2х-0,7х=2,1+0,4

-0,5х=2,5

х=2,5:(-0,5)

х=-0,5

Answer 2

Let's start by simplifying the equation using the distributive property and combining like terms:

0.2X - 0.4 = 0.7X + 2.1

Next, we'll isolate the variable terms on one side of the equation and the constant terms on the other side:

0.2X - 0.7X = 2.1 + 0.4

-0.5X = 2.5

Finally, we'll solve for X by dividing both sides by -0.5:

X = -5

Therefore, the solution to the equation 0.2*(X-2) = 0.7*(X+3) is X = -5.
