Question

ayudar a resolverlas ecuaciones de primer grados con una incógnita

4X+1=2

5X+6=10X+5

21 - 6X= 27 - 8X

8X - 4 + 3X= 7X +X+14

8X+9 - 12X= 4X - 13 -5X

Answer 1

4X+1=2 
4x = 2 - 1
4x = 1
x = 1/4

5X+6=10X+5 
5x - 10x = 5 - 6
- 5x = - 1
x = - 1/-5
x = 1/5


21 - 6X= 27 - 8X
- 6x + 8x = 27 - 21
2x = 6
x = 6/2
x = 3


8X - 4 + 3X= 7X +X+14 
11x - 4 = 8x + 14
11x - 8x = 14 + 4
3x = 18
x = 18/3
x = 6

8X+9 - 12X= 4X - 13 -5X
- 4x + 9 = - x - 13
- 4x + x = - 13 - 9
- 3x = - 22
x = - 22/-3
x = 22/3
