Question

(3x-1,4x)-0,8x-3,6=2,8

Answer 1

(3x-1,4x)-0,8x-3,6=2,8

1,6х - 0,8x-3,6=2,8

0,8х = 2,8 + 3,6

0,8x = 6.4

х = 6,4/0,8

х = 8

Answer 2

Let's solve the equation step by step:

(3x - 1, 4x) - 0.8x - 3.6 = 2.8

First, let's combine the terms on the left side:

(3x - 1.4x) - 0.8x - 3.6 = 2.8

Now, let's combine the x terms:

(3 - 1.4 - 0.8)x - 3.6 = 2.8

Now, calculate the coefficients:

(0.8)x - 3.6 = 2.8

Now, isolate the x term by adding 3.6 to both sides of the equation:

(0.8)x = 2.8 + 3.6

(0.8)x = 6.4

Finally, divide both sides by 0.8 to solve for x:

x = 6.4 / 0.8

x = 8

So, the solution to the equation is x = 8.
