Question

5(х+1)=9 3(х-4)=1 Решите уравнение.

Answer 1

Ответ:

Пошаговое объяснение:

5 (х + 1) = 9

х + 1 = 9/5

х = 9/5 - 1

х = 4/5

3(х - 4) = 1

х - 4 = 1/3

х = 1/3 + 4

х = 13/3 = 4 1/3

Answer 2

Ответ:

0,8 и 4 1/3

Пошаговое объяснение:

5(x+1)=9

5x+5=9

5x=4

X=4/5=0,8

3(x-4)=1

3x-12=1

3x=13

X=13/3=4 1/3

Answer 3

To solve the equations, we need to find the value of the variable "x" that makes each equation true. Let's start by solving each equation step by step:

1. 5(x + 1) = 9

Step 1: Distribute the 5 on the left side of the equation: 5x + 5 = 9

Step 2: Move the constant term (5) to the right side by subtracting it from both sides: 5x = 9 - 5 5x = 4

Step 3: Solve for "x" by dividing both sides by the coefficient of "x" (which is 5): x = 4/5

So, the solution for the first equation is: x = 4/5.

2. 3(x - 4) = 1

Step 1: Distribute the 3 on the left side of the equation: 3x - 12 = 1

Step 2: Move the constant term (-12) to the right side by adding it to both sides: 3x = 1 + 12 3x = 13

Step 3: Solve for "x" by dividing both sides by the coefficient of "x" (which is 3): x = 13/3

So, the solution for the second equation is: x = 13/3.

In summary:

1. For the first equation: x = 4/5.
2. For the second equation: x = 13/3.
