Question

1/2(2x + 5) - 1/4(5x - 1) = (x+2)​

Answer 1

Ответ:

x=11/5

Пошаговое объяснение:

x+9/2-5/4x+1/4=x+2

9/2-5/4x+1/4=2

19/4-5/4x=2

19-5x=8

-5x=8-19

-5x=-11

x=11/5

Answer 3

To solve the equation $\frac{1}{2}(2x + 5) - \frac{1}{4}(5x - 1) = x + 2$, you can follow these steps:

1. Distribute the fractions on the left side of the equation: $x + \frac{5}{2} - \frac{5}{4}x + \frac{1}{4} = x + 2$

2. Combine like terms on the left side of the equation: $x - \frac{5}{4}x + \frac{5}{2} + \frac{1}{4} = x + 2$

3. To make the fractions easier to work with, find a common denominator, which is 4: $\frac{4}{4}x - \frac{5}{4}x + \frac{10}{4} + \frac{1}{4} = x + 2$

4. Combine like terms on the left side: $\frac{4x - 5x + 10 + 1}{4} = x + 2$

5. Simplify the numerator on the left side: $\frac{-x + 11}{4} = x + 2$

6. To eliminate the fraction, multiply both sides of the equation by 4: $-x + 11 = 4(x + 2)$

7. Distribute on the right side: $-x + 11 = 4x + 8$

8. Add x to both sides to isolate the variable: $11 = 5x + 8$

9. Subtract 8 from both sides: $3 = 5x$

10. Finally, divide by 5 to solve for x: $x = \frac{3}{5}$

So, the solution to the equation is $x = \frac{3}{5}$.
