Question

3*а-(40-13)=3 ; (98-56):b=24:4

Answer 1

3a-27=3
3a=27+3
3a=30
a=10
Ответ: 10

Answer 2

To solve the equations, we need to find the values of the variables "а" and "b". Let's start with the first equation:

1. 3*а - (40-13) = 3

First, simplify the expression within the parentheses:

40 - 13 = 27

Now, the equation becomes:

3*а - 27 = 3

Next, isolate the variable "а" by moving the constant term to the other side:

3а = 3 + 27 3а = 30

Finally, solve for "а" by dividing both sides by 3:

а = 30 / 3 а = 10

So, the value of "а" is 10.

Now, let's move on to the second equation:

2. (98 - 56) / b = 24 / 4

First, simplify the expressions within the parentheses:

98 - 56 = 42

24 / 4 = 6

Now, the equation becomes:

42 / b = 6

Next, isolate the variable "b" by moving the constant term to the other side:

b = 42 / 6 b = 7

So, the value of "b" is 7.

In summary, the solutions to the equations are: а = 10 b = 7
