Question

Aplicando a propriedade distributiva, calcule a equação 2 (3x – 7) + 3 (x – 1) = 4 (2x – 3)

Answer 1

2 (3x – 7) + 3 (x – 1) = 4 (2x – 3)
6x - 14 + 3x - 3 = 8x - 12
9x -17 = 8x - 12
9x - 8x = -12 + 17
x = 5

Answer 2

2(3x - 7) + 3(x - 1) = 4(2x - 3)
6x - 14 + 3x - 1 = 8x - 12
6x - 8x + 3x = 1 + 14 - 12
9x - 8x = 15 - 12
            x =3
