Question

1) (x + 45) – 15 = 34; 2) (x – 56) – 24 = 17; 3) (x – 27) + 35 = 81;

Answer 1

1. (x + 45) - 15 = 34
x+45 = 34+15
x+44 = 49
x= 49-45
x= 4
Відповіть: х=4

2. (х-56) - 24 = 17
х-56= 17+24
х-56= 41+56
х= 97
Відповідь: х=97

3. (х-27)+35 = 81
х-27= 81-35
х-27= 46
х= 46+27
х= 73
Відповідь: х=73

Answer 2

Let's solve the equations step by step:

1. (x + 45) - 15 = 34

First, we simplify the equation by performing the subtraction inside the parentheses:

x + 45 - 15 = 34

Next, we simplify further by combining like terms:

x + 30 = 34

To isolate the variable x, we need to eliminate the 30 on the left side. We can do this by subtracting 30 from both sides of the equation:

x + 30 - 30 = 34 - 30

This simplifies to:

x = 4

So the solution to the equation is x = 4.

2. (x - 56) - 24 = 17

Similar to the previous equation, we simplify by performing the subtraction inside the parentheses:

x - 56 - 24 = 17

Next, we combine like terms:

x - 80 = 17

To isolate the variable x, we add 80 to both sides of the equation:

x - 80 + 80 = 17 + 80

This simplifies to:

x = 97

Therefore, the solution to the equation is x = 97.

3. (x - 27) + 35 = 81

Once again, we simplify by performing the addition inside the parentheses:

x - 27 + 35 = 81

Combining like terms, we have:

x + 8 = 81

To isolate the variable x, we subtract 8 from both sides of the equation:

x + 8 - 8 = 81 - 8

This simplifies to:

x = 73

Hence, the solution to the equation is x = 73.
