Answer 1

Ответ:

Пошаговое объяснение:

3*(6*х)+12=21

18х+12=21

18х=21-12

18х=9

х=9/18

х=1/2=0,5

Answer 2

It looks like you have an equation: $3 \times (6 \times x) + 12 = 21$, where $x$ is the unknown variable. To solve for $x$, follow these steps:

Step 1: Distribute the multiplication inside the parentheses: $3 \times 6 \times x + 12 = 21$

Step 2: Simplify the multiplication: $18x + 12 = 21$

Step 3: Subtract 12 from both sides of the equation: $18x = 21 - 12$ $18x = 9$

Step 4: Divide both sides by 18 to solve for $x$: $x = \frac{9}{18}$ $x = \frac{1}{2}$

So, the solution to the equation is $x = \frac{1}{2}$.
