\(2x+3x=30\Leftrightarrow5x=30\Leftrightarrow x=6\)
Xx(2+3)=30
Xx5=30
X=30:5
X=6
HT
TL
X x 2 + X x 3=30
X x(2+3) =30
X x 5=30
X=30:5
X=6
nha bn
HT
x . 2 + x . 3 = 30
=> x . 5 = 30
=> x = 30 : 5
=> x = 6
\(\text{X}\times2+\text{X}\times3=30.\)
\(\text{X}\times\left(2+3\right)=30\)
\(\text{X}\times5=30\)
\(\text{X}=30\div5\)
\(\text{X}=6\)
x.2+x.3=30
2x+3x=30
5x=30
x=6 nha
(x kìa ko phải tìm đâu bn ạ)
