Determina el valor de x en cada ejercicio y realiza la comprobación:
x + 9 = -10
7 x + 3 = 9x -7
9x = 3x + 18
7x + 42 = 6x + 47
42 = 6x - 18
8x + 1 = 15x - 6
4 (x - 7) = -4
x + 6 + 5x - 2 = 4(x - 2)
6x - 8 = 4 (-2x +5)
3x - 25 + 4x = 31

Respuesta:
x + 9 = -10
7 x + 3 = 9x -7
9x = 3x + 18
7x + 42 = 6x + 47
42 = 6x - 18
8x + 1 = 15x - 6
4 (x - 7) = -4
x + 6 + 5x - 2 = 4(x - 2)
6x - 8 = 4 (-2x +5)
3x - 25 + 4x = 31
Explicación paso a paso=-10+9-=1 gaaaaaaaaaaaaa reporta tu piiiiiiiiiiiiiiiiiiiiiiiiiii
Respuesta:
x + 9 = -10
x + 9 -9 = -10 -9
x = -19
7 x + 3 = 9x -7
7x + 3 -3 = 9x -7 -3
7x = 9x -10
7x -9x = 9x -10 -9x
-2x = -10
-2x/-2 = -10/-2
x = 5
9x = 3x + 18
9x -3x = 3x + 18 -3x
6x = 18
6x/6 = 18/6
x = 3
7x + 42 = 6x + 47
7x + 42 -42 = 6x + 47 -42
7x = 6x + 5
7x -6x = 6x + 5 -6x
x = 5
42 = 6x - 18
42 +18 = 6x - 18 +18
60 = 6x
60/6 = 6x/6
10 = x
x = 10
8x + 1 = 15x - 6
8x + 1 -1 = 15x - 6 -1
8x = 15x - 7
8x -15x = 15x - 7 -15x
-7x = -7
-7x/7 = -7/7
x = 1
4 (x - 7) = -4
4 (x) - (7*4) = -4
4x - 28 = -4
4x - 28 +28 = -4 +28
4x = 24
4x/4 = 24/4
x = 6
x + 6 + 5x - 2 = 4(x - 2)
x + 6 + 5x - 2 = 4(x - 2)
x + 4 + 5x = 4(x - 2)
6x + 4 = 4(x - 2)
6x + 4 = 4(x) - (2*4)
6x + 4 = 4x - 8
6x + 4 -4 = 4x - 8 -4
6x = 4x - 12
6x -4x = 4x - 12 -4x
2x = -12
2x/2 = -12/2
x = -6
6x - 8 = 4 (-2x +5)
6x - 8 = 4 * (-2x) - (4 * 5)
6x - 8 = -8x - (-20)
6x - 8 = -8x +20
6x - 8 +8 = -8x +20 +8
6x = -8x + 28
6x +8x = -8x + 28 +8x
14x = 28
14x/14 = 28/14
x = 2
3x - 25 + 4x = 31
3x - 25 + 4x = 31
7x - 25 = 31
7x -25 +25 = 31 +25
7x = 56
7x/7 = 56/7
x = 8
