РЕШИ УРАВНЕНИЯ : ( 3х+7)*2=32; (2х-20):32=6; (42+2х):2=32; (5х-7)*5=15; (13-2х)*3=27; (40-4х):2=16; КТО ПЕРВЫЙ ПОСТАВЛЮ ЛУЧШИЙ ОТВЕТ!! СРОЧНО!

Answer 1

(2х-20):32=6, 2х-20=6*32,2х-20=192, 2х=192+20, 2х=212, х=106

(42+2х):2=32, 42+2х=32*2=64,2х=64-42=22,х=11

(5х-7)*5=15,5х-7=15:5=3,5х=3+7-10,х=2

(13-2х)*3=27,13-2х=27:3=9,-2х=9-13=-4,х=-4:(-2)=2

(40-4х):2=16, 40-4х=16*2=32, -4х=32-40=-8, х=-8:(-4)=2

Answer 2

Equation 1: (3x + 7) * 2 = 32

To solve this equation, we can follow these steps:

1. Distribute the 2 to both terms inside the parentheses: 6x + 14 = 32

2. Subtract 14 from both sides of the equation: 6x = 18

3. Divide both sides of the equation by 6 to solve for x: x = 3

Therefore, the solution to the equation (3x + 7) * 2 = 32 is x = 3.

Equation 2: (2x - 20) / 32 = 6

To solve this equation, we can follow these steps:

1. Multiply both sides of the equation by 32 to eliminate the denominator: 2x - 20 = 192

2. Add 20 to both sides of the equation: 2x = 212

3. Divide both sides of the equation by 2 to solve for x: x = 106

Therefore, the solution to the equation (2x - 20) / 32 = 6 is x = 106.

Equation 3: (42 + 2x) / 2 = 32

To solve this equation, we can follow these steps:

1. Multiply both sides of the equation by 2 to eliminate the denominator: 42 + 2x = 64

2. Subtract 42 from both sides of the equation: 2x = 22

3. Divide both sides of the equation by 2 to solve for x: x = 11

Therefore, the solution to the equation (42 + 2x) / 2 = 32 is x = 11.

Equation 4: (5x - 7) * 5 = 15

To solve this equation, we can follow these steps:

1. Divide both sides of the equation by 5 to eliminate the coefficient: 5x - 7 = 3

2. Add 7 to both sides of the equation: 5x = 10

3. Divide both sides of the equation by 5 to solve for x: x = 2

Therefore, the solution to the equation (5x - 7) * 5 = 15 is x = 2.

Equation 5: (13 - 2x) * 3 = 27

To solve this equation, we can follow these steps:

1. Divide both sides of the equation by 3 to eliminate the coefficient: 13 - 2x = 9

2. Subtract 13 from both sides of the equation: -2x = -4

3. Divide both sides of the equation by -2 to solve for x: x = 2

Therefore, the solution to the equation (13 - 2x) * 3 = 27 is x = 2.

Equation 6: (40 - 4x) / 2 = 16

To solve this equation, we can follow these steps:

1. Multiply both sides of the equation by 2 to eliminate the denominator: 40 - 4x = 32

2. Subtract 40 from both sides of the equation: -4x = -8

3. Divide both sides of the equation by -4 to solve for x: x = 2

Therefore, the solution to the equation (40 - 4x) / 2 = 16 is x = 2.
