Question

7,43 - 1,28х = 1,42х+ 5=

Answer 1

7,43-1,28x=1,42x+5
-1,42x-1,28x=5-7,43
-2,7x=2,43
x=-2,43:(-2,7)
x=0,9

Answer 2

To solve this equation, we need to simplify and isolate the variable "x" on one side of the equation. We can do this by performing operations to both sides of the equation to eliminate any constants and simplify the terms with "x".

Starting with the given equation:

7.43 - 1.28x = 1.42x + 5

First, we can move the term with "x" to one side by adding 1.28x to both sides:

7.43 - 1.28x + 1.28x = 1.42x + 5 + 1.28x

Simplifying the left-hand side:

7.43 = 2.7x + 5

Next, we can move the constant term to the other side by subtracting 5 from both sides:

7.43 - 5 = 2.7x + 5 - 5

Simplifying the left-hand side:

2.43 = 2.7x

Finally, we can isolate "x" by dividing both sides by 2.7:

2.43 / 2.7 = x

Simplifying the left-hand side:

x = 0.9

Therefore, the solution to the equation is x = 0.9.
