Question

(X+3)/5=(2x-1)/12 .,.

Answer 1

$\frac{x + 3}{5} = \frac{2x - 1}{12} \: \: |60 \\ 12 \times (x + 3) = 5 \times (2x - 1) \\ 12x + 36 = 10x - 5 \\ 12x - 10x = - 5 - 36 \\ 2x = - 41 \\ x =( - 41) \div 2 \\ x = - 20.5$

Ответ : -20,5.

Answer 3

To solve the equation $\frac{X+3}{5} = \frac{2X-1}{12}$, we need to isolate $X$ on one side of the equation. We can do this by cross-multiplying or by finding a common denominator. I'll show you the cross-multiplication method.

Cross-multiplication involves multiplying the numerator of the left-hand side by the denominator of the right-hand side and the numerator of the right-hand side by the denominator of the left-hand side.

Here's the equation again: $\frac{X+3}{5} = \frac{2X-1}{12}$

Cross-multiplication: $(X+3) \times 12 = (2X-1) \times 5$

Expand both sides of the equation: $12X + 36 = 10X - 5$

Now, we want to get all the $X$ terms on one side of the equation and the constant terms on the other side. Let's move the $10X$ term to the left side by subtracting $10X$ from both sides, and let's move the constant term to the right side by subtracting $36$ from both sides:

$12X - 10X = -5 - 36$

Simplify the equation: $2X = -41$

Finally, to find the value of $X$, we divide both sides of the equation by $2$:

$X = \frac{-41}{2} = -20.5$

So the solution to the equation is $X = -20.5$.
