Question

0,35х+0,39х-120=0,26х ​

Answer 1

Ответ:

0.35x+0.39x-0.26x=120

0.48x=120

x=250

Answer 2

To solve the equation 0.35x + 0.39x - 120 = 0.26x, you need to isolate the variable x on one side of the equation. Here are the steps to do so:

Step 1: Combine like terms Combine the terms with x on the left-hand side of the equation: (0.35x + 0.39x) - 120 = 0.26x

Step 2: Simplify the left-hand side Combine the x terms: 0.74x - 120 = 0.26x

Step 3: Isolate the variable x To isolate the variable x, we need to get rid of the constant term (-120) on the left-hand side. We can do this by adding 120 to both sides of the equation: 0.74x - 120 + 120 = 0.26x + 120

Simplifying further: 0.74x = 0.26x + 120

Step 4: Move all terms with x to one side To get all terms with x on one side, we need to subtract 0.26x from both sides: 0.74x - 0.26x = 120

Simplifying further: 0.48x = 120

Step 5: Solve for x Finally, to find the value of x, divide both sides by 0.48: x = 120 / 0.48

x = 250

So, the solution to the equation is x = 250.
