Question

100/150+(50/150-x)=140/150​

Answer 1

Ответ:x = 10/150

Пошаговое объяснение:

100/150-(50/150-х)=140/150

100/150-50/150-х=140/150

150/150-х=140/150

Х=150/150-140/150

Х=10/150

Answer 2

To solve the equation, let's simplify the expression step by step:

1. Start by simplifying the left side of the equation: 100/150 + (50/150 - x)

   Since 100 and 150 have a common factor of 50, we can simplify the fraction: 2/3 + (1/3 - x)

2. Simplify the fractions within the parentheses: 2/3 + 1/3 - x

   The fractions have the same denominator, so we can combine them: (2 + 1)/3 - x

   This simplifies to: 3/3 - x

   Since 3/3 is equal to 1, we have: 1 - x

Now, the equation becomes: 1 - x = 140/150

To solve for x, we'll isolate the variable by subtracting 1 from both sides: 1 - x - 1 = 140/150 - 1

Simplifying further: -x = 140/150 - 150/150

Since 150/150 is equal to 1, we have: -x = 140/150 - 1

To subtract fractions with different denominators, we need to find a common denominator: -x = (140 - 150)/150

Simplifying the numerator: -x = -10/150

To isolate x, we'll multiply both sides by -1: x = (-10/150) * (-1)

Multiplying the numerator and denominator: x = 10/150

Simplifying the fraction: x = 1/15

Therefore, the solution to the equation is x = 1/15.
