Question

Решит уравнение x+7/12=3/4

Answer 1

х+7/12=3/4

4(x+7)=36 разделить обе стороны на 4

х+7=9

х=9-7

х=2

Answer 2

To solve the equation $x + \frac{7}{12} = \frac{3}{4}$, we need to isolate the variable $x$ on one side of the equation. Here are the steps to do that:

Step 1: Get rid of the fraction on the left side by multiplying both sides of the equation by the common denominator, which is 12.

Step 2: Simplify the equation and solve for $x$.

Let's proceed with the steps:

Step 1: Multiply both sides by 12 to eliminate the fraction: $12 \times \left(x + \frac{7}{12}\right) = 12 \times \frac{3}{4}$

Step 2: On the left side, distribute the 12: $12x + 7 = 3 \times 3$

Simplify the right side: $12x + 7 = 9$

Now, let's isolate $x$ on one side. Subtract 7 from both sides of the equation:

$12x + 7 - 7 = 9 - 7$

$12x = 2$

Finally, to find the value of $x$, divide both sides by 12:

$x = \frac{2}{12}$

Now, simplify the fraction:

$x = \frac{1}{6}$

So, the solution to the equation is $x = \frac{1}{6}$ or in decimal form $x \approx 0.1667$.
