Y ×9=15+30 12÷х+10=13 комектесши отнем

Answer 1

Ответ:

1)у×9=45

у=45÷9

у=5

5×9=15+30

45=45

2)12÷х=13-10

12÷х=3

х=12÷3

х=4

12÷4+10=13

13=13

Answer 3

Let's solve the equations:

1. $Y \times 9 = 15 + 30$

First, simplify the right side:

$15 + 30 = 45$

Now, set up the equation:

$Y \times 9 = 45$

To solve for $Y$, divide both sides by 9:

$Y = \frac{45}{9}$

$Y = 5$

So, the solution for the first equation is $Y = 5$.

2. $12 \div x + 10 = 13$

Subtract 10 from both sides:

$12 \div x = 3$

To solve for $x$, divide both sides by 3:

$x = \frac{12}{3}$

$x = 4$

So, the solution for the second equation is $x = 4$.
