Question

29х-11х=504, х+35х=2808, 7х+9х+32=272

Answer 1

29x-11x=504
18x=504
x=504/18
x=28
x+35x=2808
36x=2808
x=2808/36
x=78
7x+9x+32=272
16x=272-32
16x=240
x=240/16
x=15

Answer 2

29x-11x=504
18x=504
x=504/18
x=28
29*28-11*28=504
504=504

x+35x=2808
36x=2808
x=2808/36
x=78
78+35*78=2808
2808=2808

7x+9x+32=272
16x+32=272
16x=272-32
16x=240
x=240/16
x=15
7*15+9*15+32=272
272=272

Answer 3

To solve these equations, let's solve them one by one:

1. 29x - 11x = 504

Simplifying the left side, we have:

18x = 504

Divide both sides by 18:

x = 504 / 18

x = 28

2. x + 35x = 2808

Combining like terms on the left side, we have:

36x = 2808

Divide both sides by 36:

x = 2808 / 36

x = 78

3. 7x + 9x + 32 = 272

Combining like terms on the left side, we have:

16x + 32 = 272

Subtract 32 from both sides:

16x = 272 - 32

16x = 240

Divide both sides by 16:

x = 240 / 16

x = 15

Therefore, the solutions to the given equations are: x = 28 for the first equation, x = 78 for the second equation, and x = 15 for the third equation.
