( x + 2 ) + ( x +4 ) + ( x + 6 ) + ( x + 8 ) = 4332
=) x. (2 + 4 + 6 + 8 ) = 4332
=) x.20 = 4332
=) x = 4332 : 20
=) x =216,6
4x + (2+4+6+8)=4332
4x + 20 = 4332
4x = 4332 - 20
4x = 4312
x = 4312 : 4
x =1078
(X + 2) + (X + 4) + (X + 6) + (X + 8) = 4332
X x 4 + (2 + 4 + 6 + 8) = 4332
X x 4 + 20 = 4332
X x 4 = 4332 - 20
X x 4 = 4312
X = 4312 : 4
X = 1078
\(\left(x+2\right)+\left(x+4\right)+\left(x+6\right)+\left(x+8\right)=4332\)
\(x+2+x+4+x+6+x+8=4332\)
\(4x+20=4332\)
\(4x=4312\)
\(x=1078\)
( x + 2 ) + ( x +4 ) + ( x + 6 ) + ( x + 8 ) = 4332
<=>(x+x+x+x)+(2+4+6+8)=4332
<=>4x+20=4332
<=>4x=4312
<=>x=1078
Ta có :
4x + (2+4+6+8)=4332
4x + 20 = 4332
4x = 4332 - 20
4x = 4312
x = 4312 : 4
x =1078
