Question

(127-х):4=24 , 83-(57-х)=42

Answer 1

1) (127-х):4=24
     127-х=24*4
     127-х=96
     х=127-96
     х=31
2) 83-(57-х)=42
    57-х=83-42
    57-х=41
    х=57-41
    х=16

Answer 2

To solve these equations, we can follow these steps:

1. Solve the first equation: (127 - x) / 4 = 24

2. Solve the second equation: 83 - (57 - x) = 42

Let's start with the first equation:

(127 - x) / 4 = 24

Multiply both sides by 4 to isolate (127 - x):

127 - x = 24 * 4

127 - x = 96

Now, subtract 127 from both sides to solve for x:

-x = 96 - 127

-x = -31

Multiply both sides by -1 to get x by itself:

x = 31

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

83 - (57 - x) = 42

First, simplify the expression inside the parentheses:

83 - (57 - x) = 83 - 57 + x

Now, subtract 83 - 57:

26 + x = 42

Subtract 26 from both sides to solve for x:

x = 42 - 26

x = 16

So, the solutions to the equations are:

For the first equation: x = 31

For the second equation: x = 16
