Question

4,2(0,4х - 1) - (2,68х - 1,8) х=0,75

Answer 1

Ответ:

Пошаговое объяснение:

4,2(0,4х - 1) - (2,68х - 1,8)=

1,68х-4,2-2,68х+1,8=-х-2,4

-0,75-2,4=-3,15

Answer 2

It seems like you have an equation involving a variable "x" that you'd like to solve. Let's go through the steps to solve it:

4.2(0.4x - 1) - (2.68x - 1.8) = 0.75

First, distribute the 4.2 on the left side of the equation:

1.68x - 4.2 - (2.68x - 1.8) = 0.75

Next, remove the parentheses by distributing the negative sign on the right side:

1.68x - 4.2 - 2.68x + 1.8 = 0.75

Now, combine like terms on both sides of the equation. Group the x terms and constants separately:

(1.68x - 2.68x) + (-4.2 + 1.8) = 0.75

Simplify each group:

-1x - 2.4 = 0.75

Now, add 2.4 to both sides to isolate the x term:

-1x = 0.75 + 2.4

-1x = 3.15

Finally, divide both sides by -1 to solve for x:

x = -3.15

So, the solution to the equation is x = -3.15.
