X = 32 vì X x 4 + X x 7 = X x (4+7) = X x 11 = 352
X= 352 : 11
X = 32
\(x\times4+x\times7=352\)
\(x\times\left(4+7\right)=352\)
\(x\times11=352\)
\(x=352:11\)
\(x=32\)
Xx(4+7)=352
Xx11=352
X=352:11
X=32
\(x\times4+x\times7=352\)
\(4x+7x=352\)
\(11x=352\)
\(x=32\)
Ta có: \(x\cdot4+x\cdot7=352\)
\(\Leftrightarrow x\cdot\left(4+7\right)=352\)
\(\Leftrightarrow x\cdot11=352\)
\(\Leftrightarrow x=352\div11\)
\(\Rightarrow x=32\)
\(x\cdot4+x\cdot7=352\)
\(x\cdot\left(4+7\right)=352\)
\(x\cdot11=352\)
\(x=352:11\)
\(x=32\)
x x (4+7)=352
x x11=352
x=352:11
x=32
vậy x=32
