Question

resuelve:
3(x+2) = 5+-1
2x+3(x-1) = 6x+3
2x+3-x = 6×+1
x²-1 = 8
x³ = 8​

Answer 1

Respuesta:

3(x+2) = 5+-1

3(x+2)=5−1

3(x+2)=4

x+2=4/3

x=4/3-2

x=-2/3

2x+3(x-1) = 6x+3

2x+3x−3=6x+3

5x−3=6x+3

−3=6x+3−5x

−3=x+3

−3−3=x

−6=x

x=−6

2x+3-x = 6×+1

2x-x+3=6x+1

x+3=6·+1

x+3=7

x+3-3=7-3

x=4
