a, => 95 - 5x = 23 : 2 = 25
=> 5x = 95 - 25 = 70
=> x = 70 : 5 = 14
b, => x+2 = 316
=> x = 316 - 2 = 314
k mk nha
a) 95 - 5x = 23 + 18 : 9
\(\Leftrightarrow\)95 - 5x = 25
\(\Leftrightarrow\)5x = 95 - 25 = 70
\(\Leftrightarrow\)x = 70 : 5 =14
Vậy x = 14
b) (x + 2) = 341 + (-25)
\(\Leftrightarrow\)x + 2 = 316
\(\Leftrightarrow\)x = 316 - 2 = 314
Vậy x = 314
a)
95-5x=23+18:9
95-5x= 23 + 2
95-5x= 25
5x = 95 -25
5x = 70
x = 70 : 5
x = 14
Vậy x = 14
b)
(x+2)=341+(-25)
x+2= 316
x = 316 - 2
x = 314
Vậy x= 314
a)
95-5x=23+18:9
95-5x= 23 + 2
95-5x= 25
5x = 95 -25
5x = 70
x = 70 : 5
x = 14
Vậy x = 14
b)
(x+2)=341+(-25)
x+2= 316
x = 316 - 2
x = 314
Vậy x= 314
\(a.95-5x=23+18:9\)
\(95-5x=23+2\)
\(95-5x=25\)
\(5x=95-25\)
\(5x=70\)
\(x=70:5\)
\(x=14\)
\(\Rightarrow x=14\)
\(b.\left(x+2\right)=341+\left(-25\right)\)
\(x+2=341-25\)
\(x+2=316\)
\(x=316-2\)
\(x=314\)
\(\Rightarrow x=314\)
a)95-5x=23+18:9
95-5x=23+2
95-5x=25
5x=95-25
5x=70
x=70:5
x=14
b)(x+2)=341+(- 25)
x+2=316
x =316-2
x =314
a) \(95-5x=23+18\div9\)
\(95-5x=23+2\)
\(95-5x=25\)
\(5x=95-25\)
\(5x=70\)
\(x=70\div5\)
\(x=14\)
b) \(\left(x+2\right)=341+\left(-25\right)\)
\(x+2=316\)
\(x\) \(=316-2\)
\(x\) \(=314\)
