X x 3 + X x 5 = 9,84
X x(3+5) =9,84
X x 8 =9,84
X =9,84:8
X =1,23
\(X × 3 + X × 5 = 9,84\)
\(X×(3 + 5) =9,84\)
\(X×8=9,84\)
\(x = 9,84÷8 \)
\(x = 1,23\)
X x 3 + X x 5 = 9,84
X x (3 + 5) = 9,84
X x 8 = 9,84
X = 9,84 : 8
X = 1,23
tk cho mk nha
X x 3 + X x 5 = 9,84
X x (3 + 5) = 9,84
X x 8 = 9,84
X = 9,84 : 8
X = 1,23
