1) x = 0; 2) x = - 1; (3, 4 y 6) x = 1; 5) x = 2; 7) x = 11; 8) x = - 15; 9) x = 0; 10) x = 14,5; (11 y 12) x = 3; 13) x = 1,22...; 14) x = 4
Explicación paso a paso:
1) x + 5 = 6 - 1 2) 3x + 4 = ( 2x + 8) - ( 6 + x ) 3) 4x - 4 = 0
x + 5 = 5 3x + 4 = 2x + 8 - 6 - x 4x = 0 + 4
x = 0 3x + 4 = x + 2 4x = 4
3x - x = 2 - 4 x = 1
2x = - 2
x = - 1
4) 4x = 4 5) 6x - 2 = 10 6) 4x + 6 = x + 9
x = 1 6x = 10 + 2 4x - x = 9 - 6
6x = 12 3x = 3
x = 2 x = 1
7) 14 + x + 10 = 5 + 30 8) 18 + 2x - 8 = -25 + x 9) 12 - x = 3 - 2x + 9
x + 24 = 35 2x + 10 = - 25 + x 12 - x = 12 - 2x
x = 35 - 24 2x - x = - 25 - 10 - x + 2x = 12 - 12
x = 11 x = - 35 x = 0
10) 2x - 2 = 27 11) 7x + 4 = 13 + 4x 12) 10x = 27 + 3
2x = 27 + 2 7x - 4x = 13 - 4 10x = 30
2x = 29 3x = 9 x = 3
x = 14,5 x = 3
13) x - 15 + ( x + 4 ) = 3( 2x - 1) 14) 4 ( 6 + 2x ) + 5 ( 2 - x ) = - 3 ( x + 6 ) - 8
2x - 11 = 6x - 6 24 + 8x + 10 - 5x = - 3x + 18 - 8
- 11 + 6 = 6x - 2x 34 + 3x = -3x + 10
- 5 = 4x 3x + 3x = 10 - 34
1, 22... = x 6x = - 24
x = 4
