Question

А)0,7*х=-1,4 Б)5,4-1,5х=0,3х-3,6

Answer 1

Ответ:

-2, 5

Пошаговое объяснение:

а)0,7*х=-1,4

х=-1,4:0,7

х=-2

б)5,4-1,5х=0,3х-3,6

1,5х+0,3х=5,4+3,6

1,8х=9

х=9:1,8

х=5

Answer 2

Let's solve the two equations you provided:

А) 0.7 * x = -1.4

To solve for x, divide both sides of the equation by 0.7:

x = -1.4 / 0.7

x = -2

So the solution to equation A is x = -2.

Б) 5.4 - 1.5x = 0.3x - 3.6

To solve for x, we need to simplify the equation and isolate x on one side. First, let's move all the x terms to one side and the constant terms to the other side:

5.4 + 3.6 = 0.3x + 1.5x

9 = 1.8x

Now, divide both sides by 1.8 to solve for x:

x = 9 / 1.8

x = 5

So the solution to equation B is x = 5.

To summarize: A) x = -2 Б) x = 5
