Answer 1

(5+x)*5=(3x+6)*2=
25+5x=6x+12
13=1x
2)(4x+6)*3=2x*(2+9)
12x+18=22x
10x=18
x=1,8
3)6х-4-5х=2
х=6

Answer 2

1) To solve the equation 5 + x/2 = 3x + 6/5, we can follow these steps:

Step 1: Multiply through by the common denominator to eliminate the fractions. In this case, the common denominator is 10.

10(5 + x/2) = 10(3x + 6/5)

Step 2: Simplify both sides of the equation.

50 + 5x = 30x + 12

Step 3: Move all the terms with x to one side of the equation and the constant terms to the other side.

5x - 30x = 12 - 50

-25x = -38

Step 4: Divide both sides of the equation by -25 to solve for x.

x = -38 / -25

x = 1.52

Therefore, the solution to the equation 5 + x/2 = 3x + 6/5 is x = 1.52.

2) To solve the equation 4x + 6/2 + 9 = 2x/3 + 3, we can follow these steps:

Step 1: Multiply through by the common denominator to eliminate the fractions. In this case, the common denominator is 6.

6(4x + 6/2 + 9) = 6(2x/3 + 3)

Step 2: Simplify both sides of the equation.

24x + 18 + 54 = 4x + 18

Step 3: Combine like terms on both sides of the equation.

24x + 72 = 4x + 18

Step 4: Move all the terms with x to one side of the equation and the constant terms to the other side.

24x - 4x = 18 - 72

20x = -54

Step 5: Divide both sides of the equation by 20 to solve for x.

x = -54 / 20

x = -2.7

Therefore, the solution to the equation 4x + 6/2 + 9 = 2x/3 + 3 is x = -2.7.

3) To solve the equation 6x - 4 - 5x = 2, we can follow these steps:

Step 1: Combine like terms on both sides of the equation.

6x - 5x - 4 = 2

Step 2: Simplify both sides of the equation.

x - 4 = 2

Step 3: Move the constant term to the other side of the equation.

x = 2 + 4

x = 6

Therefore, the solution to the equation 6x - 4 - 5x = 2 is x = 6.

I hope this helps! Let me know if you have any further questions.
