Question

4(1.x)-2x+1=-3(2+x) qual a resposta?

Answer 1

4 (1 + x) - 2x + 1 = -3 (2 + x)
4 + 4x - 2x + 1 = -6 - x
4 + 1 + 6 = - x - 4x + 2x
11 = -3x
x = 11/-3

Answer 2

4(1.x)-2x+1= -3(2+x)
4.4x-2x+1= -6-3x
4.4x-2x+3x+1+6=0
4.5x+7=0
20x+7=0
a=0  b=20  c=7
delta=b²-4.a.c
delta=20²-4.0.7
delta=400
Resposta é 20
