a, \(x-\left(36:18\right)=12\)
\(x-2=12\)
\(x=12+2\)
\(x=14\)
b, \(\left(x-36\right):18=12\)
\(x-36=12.18\)
\(x-36=216\)
\(x=216+36\)
\(x=252\)
a, x-36:18=12
=> x-2=12
=> x=12+2
=> x=14
b, (x-36):18=12
=> x-36=12.18
=> x-36=216
=> x=216+36
=> x=252
\(a,\left(x-\dfrac{5}{8}\right).\dfrac{5}{8}=-\dfrac{15}{36}\)
\(\left(x-\dfrac{5}{8}\right)=-\dfrac{15}{36}\div\dfrac{5}{8}\)
\(x-\dfrac{5}{8}=-\dfrac{2}{3}\)
\(x=-\dfrac{2}{3}+\dfrac{5}{8}\)
\(x=-\dfrac{1}{24}\)
\(b,\left(x-\dfrac{1}{3}\right)=\dfrac{5}{6}\)
\(\Rightarrow x-\dfrac{1}{3}=\dfrac{5}{6}\)
\(x=\dfrac{5}{6}+\dfrac{1}{3}\)
\(x=\dfrac{7}{6}\)
\(a,\left(x-\dfrac{5}{8}\right)\cdot\dfrac{8}{18}=-\dfrac{15}{16}\\ x-\dfrac{5}{8}=-\dfrac{15}{36}:\dfrac{8}{18}\\ x-\dfrac{5}{8}=-\dfrac{15}{16}\\ x=-\dfrac{15}{16}+\dfrac{5}{8}\\ x=-\dfrac{15}{16}+\dfrac{10}{16}\\ x=-\dfrac{5}{16}\\ b,x-\dfrac{1}{3}=\dfrac{5}{6}\\ x=\dfrac{5}{6}+\dfrac{1}{3}\\ x=\dfrac{5}{6}+\dfrac{2}{6}\\ x=\dfrac{7}{6}\)
\(\left(\dfrac{103}{8}-\dfrac{193}{18}\right):x-\dfrac{40}{33}:\dfrac{8}{11}=\dfrac{5}{3}\)
\(\dfrac{155}{72}:x-\dfrac{5}{3}=\dfrac{5}{3}\)
\(\dfrac{155}{72}:x=\dfrac{5}{3}+\dfrac{5}{3}=\dfrac{10}{3}\)
\(x=\dfrac{155}{72}:\dfrac{10}{3}=\dfrac{31}{48}\)

(x – 36) : 18 = 12
x – 36 = 12.18
x – 36 = 216
x = 216 + 36
x = 252
Vậy x = 252
x - 36 : 18 = 12
=> x - 2 = 12
=> x = 14
vậy_
(x - 36) : 18 = 12
=> x - 36 = 216
=> x = 252
vậy_
b) x - 36 : 18 = 12
x - 2 = 12
x = 14
b) (x-36) : 18 = 12
x - 36 = 216
x = 252
a,x-36:18=12
\(\Rightarrow\)x-2=12
\(\Rightarrow\)x=12+2
\(\Rightarrow\)x=14
b,(x-36):18=12
\(\Rightarrow\)x-36=18.12
\(\Rightarrow\)x-36=216
\(\Rightarrow\)x=216+36
\(\Rightarrow\)x=252
\(x-36:18=12\)
\(x-2=12\)
\(x=12+2\)
\(x=14\)
\(\left(x-36\right):18=12\)
\(\left(x-36\right)=12\times18\)
\(x-36=216\)
\(x=216+36\)
\(x=252\)
( X-36 ) / 18 = 12 X-36 =12*18 X =216 X =216+36 X =252
