Answer 3

To solve each of the equations, we need to find the value of 'x'. Let's go through each one step by step:

А) 9x = -54

To find 'x', we need to isolate it on one side of the equation. We can do this by dividing both sides by 9:

9x / 9 = -54 / 9

x = -6

So, the solution for equation (A) is x = -6.

б) -0.7x = 1.4

To find 'x', we need to isolate it on one side of the equation. We can do this by dividing both sides by -0.7:

(-0.7x) / -0.7 = 1.4 / -0.7

x = -2

So, the solution for equation (б) is x = -2.

в) 7.5x = -15

To find 'x', we need to isolate it on one side of the equation. We can do this by dividing both sides by 7.5:

(7.5x) / 7.5 = -15 / 7.5

x = -2

So, the solution for equation (в) is x = -2.
