Question

3x + 7 = 34
24-5x = 40 +2x
5x + 26 = 2x + 56
45-7x=75-3
5x+4>3x+30
25-7x>34-3x

Answer 1

3x = 34-7
x = 9

24-5x = 40+2x
-7x = 16
22,8

5x+26=2x+56
3x = 30
10

45-7x = 75-3
-7X= 75-45-3
-7x= 17
x= 24,5

Answer 2

3x + 7 = 343x = 34-7
3x = 27
x = 9

24-5x = 40 +2x
-5x-2x = 40-24
-7x = 16
x = -16/7

5x + 26 = 2x + 56
5x-2x = 56-26
3x = 30
x = 10

45-7x = 75-3
-7x = 75-3-45
-7x = 27
x = -27/7

5x+4 > 3x+30
5x-3x > 30-4
2x > 26
x > 13

25-7x > 34-3x
-7x+3x > 34-25
-4x > 9
x < -9/4
