b/2.x-18=20
c/134-5.(x+4)=34
dấu chấm là dấu nhân nhìn thật kĩ giúp mình nhé love you
\(\text{a/96-3(x+1)=42}\)
\(3\left(x+1\right)=54\)
\(x+1=54:3\)
\(x+1=18\)
\(\Rightarrow x=17\)
\(\text{b/2.x-18=20}\)
\(2x=38\)
\(x=38:2\)
\(x=19\)
\(\text{c/134-5.(x+4)=34}\)
\(5\left(x+4\right)=100\)
\(x+4=100:5\)
\(x+4=20\)
\(\Rightarrow x=16\)

k nha ^_-

k mình nha !!!
tính :
x – (-18) = 134 − (34 – 91)
4x + (-188) = - 358 + (458 – 124)
\(x-\left(-18\right)=134-\left(34-91\right)\)
⇔\(x+18=134-34+91\)
⇔\(x+18=191\)
⇔\(x=173\)
\(4x+\left(-188\right)=-358+\left(458-124\right)\)
⇔\(4x-188=-358+458-124\)
⇔\(4x-188=-24\)
⇔\(4x=164\)
⇔\(x=41\)
+) x-(-18) = 134 - (34-91)
<=> x +18 = 191
<=> x= 173
+) 4x+(-188) = -358 + (458 - 124)
