Question

12 + 4x = 6x + 10 - 2x

5x + 14 - 4x = 23 + x -9

x+9 -0.8x = 5.2x + 17-8

4x-2x = 20
Witch equals infinity many solutions

Answer 1

2nd equation: 5x + 14 - 4x = 23 + x - 9

Explanation:

12+4x=6x+10-2x

12+4x=4x+10

12=10

No solutions

5x+14-4x=23+x-9

x+14=14+x

x=x

Infinitely many solutions

x+9-0.8x=5.2x+17-8

0.2x+9=5.2x+9

0.2x=5.2x

0=5x

0=x

One solution

4x-2x=20

2x=20

x=10
