Question

2,5(2x+2) + 0,2 (x+1,5) = 6,6​

Answer 1

5х+5+0,2х+0,3=6,6
5,2х+5,3=6,6
5,2х=6,6-5,3
5,2х=1,3
х=1,3/5,2
х=0,25

Answer 2

To solve the equation 2.5(2x+2) + 0.2(x+1.5) = 6.6, you'll want to simplify and isolate the variable x. Here's how you can do it step by step:

1. Distribute the constants on the left side of the equation: 5x + 5 + 0.2x + 0.3 = 6.6

2. Combine like terms on the left side of the equation: (5x + 0.2x) + (5 + 0.3) = 6.6 5.2x + 5.3 = 6.6

3. Now, subtract 5.3 from both sides of the equation to isolate the variable term: 5.2x = 6.6 - 5.3 5.2x = 1.3

4. Finally, divide both sides by 5.2 to solve for x: x = 1.3 / 5.2 x = 0.25

So, the solution to the equation is x = 0.25.
