В) 6х+4х+х=77уравнение 5 класс

Answer 1

6х+4х+х=77

11х=77

х=7

6+4+1=11 и 77 нужно делить на 11

Answer 2

6х+4х+х=77
(6+4+1)х=77
11х=77
х=77:11
х=7
Проверка:
6*7+4*7+7=77
42+28+7=77
70+7=77
77=77 верно
Ответ: х=7

Answer 3

To solve the equation $6x + 4x + x = 77$ for $x$, we first need to combine like terms on the left side of the equation. Like terms are terms that have the same variable and the same exponent.

Combining the terms with $x$:

$6x + 4x + x = 11x$

Now, the equation becomes:

$11x = 77$

To isolate $x$, we can divide both sides of the equation by 11:

$\frac{{11x}}{{11}} = \frac{{77}}{{11}}$

$x = 7$

So the solution to the equation is $x = 7$.
