Question

10/15+[5/15-х]=14/15

Answer 1

10/15+(5/15-x)=14/15
10/15+(1/3-x)=14/15
10/15+1/3-x=14/15
1-x=14/15
-x=14/15
-x=14/15-1
-x=-1/15
x=1/15

Answer 2

Пошаговое объяснение:

10/15+[5/15-х]=14/15

расроем модуль в уравнени и получим :

10/15+5/15-х=14/15

15/15-х=14/15

х= 15/15-14/15

х=1/15

Answer 3

To solve the equation, let's break it down step by step:

10/15 + (5/15 - x) = 14/15

First, let's simplify the expression within the parentheses:

10/15 + (5/15 - x) = 14/15

The common denominator for 5/15 and x is 15, so we can rewrite the expression as:

10/15 + (5 - 15x)/15 = 14/15

Next, let's combine the fractions on the left side:

(10 + 5 - 15x)/15 = 14/15

Simplifying further:

(15 - 15x)/15 = 14/15

Now, cross-multiply:

15 * 14 = (15 - 15x) * 15

210 = 15 - 15x

Next, let's isolate the variable by subtracting 15 from both sides:

210 - 15 = -15x

195 = -15x

To solve for x, divide both sides by -15:

195 / -15 = x

x = -13

Therefore, the solution to the equation is x = -13.
