Question

2(х-3)=6; 5(2х-1)-7-х=0; (х-2)4=15; 3(х-3)-5-(2х-5)4=0 помогите пожалуйста плиз

Answer 1

2x-6=6         10х-5-7-х=0    4х-8=15           3х-9-5-8х-20=0
2х=6-6         10х-х=5+7      4х=15+8          3х-8х=9+5+20
2х=0            9х=12             4х=23             -5х=34
х=0/2           х=12/9            х=23/4             х=-34/5
х=0              х=1 3/9           х=5 3/4            х=-6 4/5

Answer 2

Equation 1: 2(х-3)=6

To solve this equation, we can follow these steps:

Step 1: Distribute the 2 to both terms inside the parentheses: 2 * x - 2 * 3 = 6

Step 2: Simplify the equation: 2x - 6 = 6

Step 3: Add 6 to both sides of the equation to isolate the variable: 2x - 6 + 6 = 6 + 6 2x = 12

Step 4: Divide both sides of the equation by 2 to solve for x: 2x/2 = 12/2 x = 6

Therefore, the solution to the equation 2(х-3)=6 is x = 6.

Equation 2: 5(2х-1)-7-х=0

To solve this equation, we can follow these steps:

Step 1: Distribute the 5 to both terms inside the parentheses: 5 * 2x - 5 * 1 - 7 - x = 0

Step 2: Simplify the equation: 10x - 5 - 7 - x = 0

Step 3: Combine like terms: 9x - 12 = 0

Step 4: Add 12 to both sides of the equation to isolate the variable: 9x - 12 + 12 = 0 + 12 9x = 12

Step 5: Divide both sides of the equation by 9 to solve for x: 9x/9 = 12/9 x = 4/3

Therefore, the solution to the equation 5(2х-1)-7-х=0 is x = 4/3.

Equation 3: (х-2)4=15

To solve this equation, we can follow these steps:

Step 1: Distribute the 4 to the term inside the parentheses: 4 * (x - 2) = 15

Step 2: Simplify the equation: 4x - 8 = 15

Step 3: Add 8 to both sides of the equation to isolate the variable: 4x - 8 + 8 = 15 + 8 4x = 23

Step 4: Divide both sides of the equation by 4 to solve for x: 4x/4 = 23/4 x = 23/4

Therefore, the solution to the equation (х-2)4=15 is x = 23/4.

Equation 4: 3(х-3)-5-(2х-5)4=0

To solve this equation, we can follow these steps:

Step 1: Distribute the 3 to the term inside the first set of parentheses and the 4 to the term inside the second set of parentheses: 3x - 9 - 5 - (8x - 20) = 0

Step 2: Simplify the equation: 3x - 14 - 8x + 20 = 0

Step 3: Combine like terms: -5x + 6 = 0

Step 4: Subtract 6 from both sides of the equation to isolate the variable: -5x + 6 - 6 = 0 - 6 -5x = -6

Step 5: Divide both sides of the equation by -5 to solve for x: -5x/-5 = -6/-5 x = 6/5

Therefore, the solution to the equation 3(х-3)-5-(2х-5)4=0 is x = 6/5.
