Question

1. 7+х=42. -24-у=-16​

Answer 1

Ответ:

1. 7+х=4

х=7-4

х=3

2. -24-у=-16

-у=-16+24

-у=8

у=-8

Answer 2

To solve the system of equations:

1. 7 + x = 42
2. -24 - y = -16

Let's first solve each equation separately:

1. 7 + x = 42

To isolate the variable x, you can subtract 7 from both sides of the equation:

7 + x - 7 = 42 - 7

This simplifies to:

x = 35

So, the solution for the first equation is x = 35.

2. -24 - y = -16

To isolate the variable y, you can add 24 to both sides of the equation:

-24 + 24 - y = -16 + 24

This simplifies to:

-y = 8

Now, to solve for y, you can multiply both sides by -1 to change the sign:

(-1)(-y) = (-1)(8)

This simplifies to:

y = -8

So, the solution for the second equation is y = -8.

Therefore, the solution to the system of equations is x = 35 and y = -8.
