Question

99-(у-28)=13103-(z+47 )=54​

Answer 1

Пошаговое объяснение:

99-у+28=13

-у=13-99-28

у=114

103-z-47=54

-z=54-103+47

z=2

Answer 2

To solve this system of equations:

1. 99 - (у - 28) = 13103 - (z + 47) = 54

First, let's simplify each part of the equation step by step:

For the first part: 99 - (у - 28)

We can distribute the negative sign inside the parentheses:

99 - у + 28

Combine like terms:

127 - у

Now, for the second part: 13103 - (z + 47)

Distribute the negative sign inside the parentheses:

13103 - z - 47

Combine like terms:

13056 - z

So, now we have two expressions equal to 54:

1. 127 - у = 54
2. 13056 - z = 54

Let's solve each equation separately:

1. 127 - у = 54

Subtract 127 from both sides:

-у = 54 - 127 -у = -73

Now, divide both sides by -1 to isolate у:

у = 73

2. 13056 - z = 54

Subtract 13056 from both sides:

-z = 54 - 13056 -z = -12902

Now, divide both sides by -1 to isolate z:

z = 12902

So, the solutions to the system of equations are у = 73 and z = 12902.
