Question

3×Х+50=77,100-24÷С=92,3×Х=92-68

Answer 1

3×Х+50=77
3× х=77-50
3×х=27
х=27÷3
х=9

100-24÷С=92
24÷с=100-92
24÷с=8
с=24÷8
с=3

3×Х=92-68
3×х=24
х=24÷3
х=8

Answer 3

Let's solve the equations step by step:

1. 3×X + 50 = 77,100

To isolate X, we subtract 50 from both sides:

3×X = 77,100 - 50 3×X = 77,050

Divide both sides by 3:

X = 77,050 ÷ 3 X ≈ 25,683.33

Therefore, X is approximately 25,683.33.

2. 100 - 24÷C = 92

To isolate C, we start by solving the division:

24 ÷ C = 100 - 92 24 ÷ C = 8

To get rid of the division, we can multiply both sides by C:

24 = 8×C

Divide both sides by 8:

C = 24 ÷ 8 C = 3

Therefore, C equals 3.

3. 3×X = 92 - 68

Subtract 68 from 92:

3×X = 24

Divide both sides by 3:

X = 24 ÷ 3 X = 8

Therefore, X equals 8.

To summarize the solutions: X ≈ 25,683.33 C = 3 X = 8
