х+24=50-20

х+24=30

х=30-24

х=6

Answer 3

Let's solve each equation step by step:

1. X - (23 + 17) = 60

First, solve the parentheses:

X - (23 + 17) = X - 40

Now, the equation becomes:

X - 40 = 60

Next, isolate X by moving -40 to the other side of the equation:

X = 60 + 40

X = 100

So, the solution for X is 100.

2. (30 - 15) + y = 80

First, solve the parentheses:

(30 - 15) + y = 15 + y

Now, the equation becomes:

15 + y = 80

Next, isolate y by moving 15 to the other side of the equation:

y = 80 - 15

y = 65

So, the solution for y is 65.

3. x + 12 + 12 = 50 - (15 + 5)

First, solve the parentheses:

x + 12 + 12 = 50 - 20

Now, the equation becomes:

x + 24 = 30

Next, isolate x by moving 24 to the other side of the equation:

x = 30 - 24

x = 6

So, the solution for x is 6.

To summarize:

1. X = 100
2. y = 65
3. x = 6
