Answer 2

Відповідь:

A-39=128

a=128+39

a=167

127-b=54

b=127-54

b=73

(135+x)-258=104

135+x=104+258

135+x=362

x=362-135

x=227

Answer 3

To solve these equations, let's break them down one by one:

1. A - 39 = 128

To find the value of A, add 39 to both sides of the equation:

A - 39 + 39 = 128 + 39

A = 167

So, A = 167.

2. 127 - b = 54

To find the value of b, subtract 54 from both sides of the equation:

127 - b - 54 = 54 - 54

• b = -27

Now, multiply both sides by -1 to isolate b:

-1 * (-b) = -1 * (-27)

b = 27

So, b = 27.

3. (135 + x) - 258 = 104

First, add 258 to both sides of the equation:

(135 + x) - 258 + 258 = 104 + 258

135 + x = 362

Now, subtract 135 from both sides to isolate x:

135 + x - 135 = 362 - 135

x = 227

So, x = 227.

The solutions to the equations are:

A = 167 b = 27 x = 227
