Question

8/15x-3/10x+3/5x=1/2

Answer 1

8/15х-3/10х+3/5х=1/2

16/30х-9/30х+18/30=15/30

25/30х=15/30

Х=15/30*30/25

Х=15/25

Х=3/5

Х=0,6

Answer 2

Ответ:

8/15x-3/10x+3/5x=1/2

x×(8/15-3/10+3/5)=1/2

x×(16/30-9/30+18/30)=1/2

x×25/30=1/2

x=1/2÷25/30

x=15/25

Answer 3

To solve the equation, we need to find the value of x that makes the equation true. Let's simplify the equation step-by-step:

Step 1: Combine the like terms on the left side of the equation. (8/15)x - (3/10)x + (3/5)x = 1/2

To combine the x terms, we need to find a common denominator. The least common multiple of 15, 10, and 5 is 30. So, let's rewrite the equation with a common denominator of 30:

Step 2: Rewrite the equation with a common denominator of 30. (8/15 * 30)x - (3/10 * 30)x + (3/5 * 30)x = 1/2 * 30

Step 3: Simplify the equation. (16x) - (9x) + (18x) = 15

Step 4: Combine the x terms on the left side of the equation. 16x - 9x + 18x = 15

Step 5: Simplify the equation further. 25x = 15

Step 6: Isolate x by dividing both sides by 25. x = 15 / 25

Step 7: Simplify the fraction. x = 3/5

So, the value of x that satisfies the equation is x = 3/5.
