Question

[x+2]+[x+4]+[x+6]+[x+8]=4332

Giá trị của x là ?

Answer 1

(x+2)+(x+4)+(x+6)+(x+8)=4322

x+2+x+4+x+6+x+8=4322

4x+2+4+6+8=4322

4x+20=4332

4x=4332-20

4x=4312

x=4312:4

x=1078

Answer 2

[x+2]+[x+4]+[x+6]+[x+8]=4332 

=) x + 2 + x + 4 + x + 6 + x + 8 = 4332 

=) 4x + 20 = 4332 

=) 4x = 4332 - 20

=) 4x = 4312

=) x = 4312 / 4 

=) x = 1078 

Answer 3

(X+2)+(X+4)+(X+6)+(X+8)=4332

X+2+X+4+X+6+X+8=4332

Xx4=4332-2-4-6-8

Xx4=4312

X=4312:4

X=1078
