Ejercicios de Ecuaciones Lineales
1. 2x + 4 =
2x + 4 = 8
2x = 8 – 4
2x = 4
X = 4/2
X = 2
2. 5x + 3 =
5x + 3 = 15
5x = 15 – 3
5x = 12
X = 12/5
X = 2.4
3. 4x – 8 =
4x – 8 = -32
4x = -32 + 8
4x = -24
X = -24/4
X = -6
4. 2x – x = 6 + 3
2(2x – 3) = 6 + x
4x – 6 = 6 + x
4x – x = 6 + 6
3x = 12
X = 12/3
X = 4
5. 4x – 2 = 8 + x
4x – x = 8 + 2
4(4x – 2) = 8 + x
16x – 8 = 8 + x
16x – x = 8 + 8
15x = 16
X = 16/15
X = 1.06
Ejercicios Ecuaciones de primer grado
6. 8 – 5x = 8 + 2x
-5x -2x = 8 – 8
-7x = 0
X = 0/7
X = 0
7. 12 – 8x = 9 + 4x
-8x -4x = 9 – 12
-12x = -3
X = -3/-12
X = 0.25
8. 5(x – 3) + 8x = 6x – 5 + x
5x – 15 + 8x = 7x – 5
5x + 8x -7x = -5 + 15
6x = 10
