Question

2 (2x+7) + 3 (3x-5) =3 (4x-5)-1

Answer 1

2(2x+7)+3(3x-5)=3(4x-5)-1
4x+14+9x-15=12x-15-1
13x-1=12x-16
13x-12x=-16+1
x=-15

Answer 2

Devemos aplicar a distributiva

2.(2x + 7) + 3 . (3x - 5) = 3.(4x - 5) -1
4x + 14 + 9x - 15 = 12x - 15 - 1
4x + 9x + 14 - 15 = 12x - 16
13x - 1 = 12x - 16
13x - 12x = - 16 + 1
x = -15

Resposta: - 15
