Question

Ayudenme con esta ecuacion
8x +[6x - (2x - 3 )] = 10x + 7

Answer 1

8x +[6x - (2x - 3 )] = 10x + 7 
8x + [ 6x -2x+3 ] = 10x + 7 
8x +4x+3 = 10x + 7 
12x + 3 = 10x + 7 
12x - 10x = 7 - 3 
2x = 4 
x = 2 

Answer 2

Solución:

8x + [6x - (2x - 3 )] = 10x + 7
8x + [6x - 2x + 3 ] = 10x + 7
8x + [4x + 3] = 10x + 7
8x + 4x + 3 = 10x + 7
12x - 10x = 7 - 3
2x = 4
x = 4/2
x = 2

Verificamos:

8x + [6x - (2x - 3 )] = 10x + 7
8(2) + [6(2) - (2(2) - 3 )] = 10(2) + 7
16 + [12 - (4 - 3)] = 20 + 7
16 + [12 - (1)] = 27
16 + [12 - 1] = 27
16 +[11] = 27
16 + 11 = 27
27 = 27
Igualdad Verdadera
