0,5х-2,5-0,4х+1,2=1,6

0,1х=2,5-1,2+1,6

х=25-12+16

х=29

Answer 3

To solve the equation, let's simplify the expression step by step and then isolate the variable "x."

Step 1: Distribute the constants outside the parentheses to the terms inside the parentheses.

5(0.1x - 0.5) - 0.4(x - 3) = 1.6

Step 2: Perform the multiplication inside the parentheses.

0.5x - 2.5 - 0.4x + 1.2 = 1.6

Step 3: Combine like terms (0.5x and -0.4x) and (-2.5 and +1.2).

(0.5x - 0.4x) - (2.5 - 1.2) = 1.6

0.1x - 1.3 = 1.6

Step 4: Move the constant term (-1.3) to the right side of the equation by adding 1.3 to both sides.

0.1x = 1.6 + 1.3

0.1x = 2.9

Step 5: Finally, isolate the variable "x" by dividing both sides by 0.1.

x = 2.9 / 0.1

x = 29

So, the solution to the equation is x = 29.
