Question

2x+1/7 - X-1/4=1 / - дробь

Answer 1

Кривой ответ. там точно дроби 1/7 и 1/4? или там все под дробью

Answer 2

To solve the equation, let's first simplify the expression:

2x + 1/7 - x - 1/4 = 1/(-1/1)

To simplify the right side, we need to find the reciprocal of -1/1, which is -1.

Now we have:

2x + 1/7 - x - 1/4 = -1

Combining like terms on the left side:

(2x - x) + 1/7 - 1/4 = -1

x + 1/7 - 1/4 = -1

Now let's find a common denominator for 7 and 4, which is 28:

(28x + 4)/28 - (7 + 1)/28 = -1

Combining the numerators over the common denominator:

(28x + 4 - 8 - 7)/28 = -1

Simplifying:

(28x - 11)/28 = -1

Now we can cross-multiply:

28x - 11 = -28

Adding 11 to both sides:

28x = -17

Dividing both sides by 28:

x = -17/28

Therefore, the solution to the equation is x = -17/28.
