Question

3/4х-(0,25х-3)=1,2 Пжжжж

Answer 1

Ответ:

-3,6

Пошаговое объяснение:

3/4х-1/4х+3=12/10

2/4х+3=6/5

1/2х=6/5-3

1/2х=6/5-15/5

1/2х=-9/5

х=-9/5*2=-18/5=-3,6

Answer 2

Sure, I can help you solve the equation:

3/4x - (0.25x - 3) = 1.2

To solve the equation, follow these steps:

Step 1: Distribute the negative sign through the parentheses:

3/4x - 0.25x + 3 = 1.2

Step 2: Combine like terms on the left side of the equation:

(3/4 - 0.25)x + 3 = 1.2

Step 3: Simplify the coefficient of x:

(0.75)x + 3 = 1.2

Step 4: Now, isolate the term with x. Subtract 3 from both sides:

(0.75)x = 1.2 - 3

Step 5: Simplify the right side of the equation:

(0.75)x = -1.8

Step 6: To solve for x, divide both sides by 0.75:

x = -1.8 / 0.75

Step 7: Perform the division:

x = -2.4

So, the solution to the equation is x = -2.4.
