Question

11/15-(х+7/15)=1/15 ; (5/24+х)-3/24=19/24

Answer 1

Ответ:

(X+5/12)-9/20=11/15

х+5/12=11/15+9/20

х+5/12=142/120=71/60

х=71/60-5/12

х=46/60=23/30 вот 1

Answer 2

1) Ответ:

х=1/5

Решение:

11/15-(х+7/15)=1/15

11/15-х+7/15=1/15

4/15-х=1/15

-х=1/15 - 4/15

-х=-1/5

х=1/5

2) Ответ:

х = 17/24

Решение:

(5/24+х)-3/24=19/24

5/24+х-3/24=19/24

1/12+х=19/24

х=19/24-1/12

х=17/24

Answer 3

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

1. 11/15 - (x + 7/15) = 1/15

Step 1: Combine like terms on the left side. 11/15 - x - 7/15 = 1/15

Step 2: Get rid of the constant on the left side by subtracting 11/15 from both sides. (-x - 7/15) = 1/15 - 11/15

Step 3: Simplify the right side. -x - 7/15 = -10/15

Step 4: To get rid of the fraction on the left side, multiply both sides by 15. 15 * (-x - 7/15) = 15 * (-10/15)

Step 5: Simplify both sides. -15x - 7 = -10

Step 6: Move the constant to the right side by adding 7 to both sides. -15x = -10 + 7 -15x = -3

Step 7: Solve for x by dividing both sides by -15. x = -3 / -15 x = 1/5

So the solution for the first equation is x = 1/5.

2. (5/24 + x) - 3/24 = 19/24

Step 1: Combine like terms on the left side. 5/24 + x - 3/24 = 19/24

Step 2: Get rid of the constant on the left side by adding 3/24 to both sides. (5/24 + x) = 19/24 + 3/24

Step 3: Simplify the right side. (5/24 + x) = 22/24

Step 4: To get rid of the fraction on the left side, subtract 5/24 from both sides. (5/24 + x) - 5/24 = 22/24 - 5/24

Step 5: Simplify both sides. x = 17/24

So the solution for the second equation is x = 17/24.

To summarize:

1. x = 1/5
2. x = 17/24
