88-3(7+x)=64
88 - ( 7 + Y ) x 3 = 64
\(88-\left(7+y\right)\cdot3=64\)
\(\Rightarrow\left(7+y\right)\cdot3=88-64\)
\(\Rightarrow\left(7+y\right)\cdot3=24\)
\(\Rightarrow7+y=24:3\)
\(\Rightarrow7+y=8\)
\(\Rightarrow y=8-7\)
\(\Rightarrow y=1\)
\(\Leftrightarrow3\left(y+7\right)=24\Leftrightarrow y+7=8\Leftrightarrow y=1\)
Vậy, y=1
Tìm x biết :88-3(7+ x)bằng 64
\(88-3\left(7+x\right)=64\)
\(\Rightarrow-3\left(7+x\right)=64-88\)
\(\Rightarrow7+x=\frac{-24}{-3}=8\)
\(\Rightarrow x=8-7=1\)

trả lời nhanh giúp mình với:
7 * x - 8. 713
720 : [41 - 2 * x - 5] = 8 * 5
88 - 3 * (7 + x) = 64
[(x * 32) - 17 ] x 2 = 42
( ( x . 32 ) - 17 ) . 2 = 42
( ( x . 32 ) - 17 ) = 42 : 2
( ( x . 32 ) - 17 ) = 21
x . 32 = 21 + 17
x . 32 = 38
x = 38 : 32
x = 19/16
88 - 3 . ( 7 + x ) = 64
3 . ( 7 + x ) = 88 - 64
3 . ( 7 + x ) = 24
7 + x = 24 : 3
7 + x = 8
x = 8 - 7
x = 1
88-3.(7+x)=64
giai giup minh voi
rõ lời giải nha
88-3.(7+x)=64
3(7+x) = 88-64
3(7+x) = 24
7+x = 24:3
7+x = 8
x= 8-7
x=1
88-3(7+x)=64
3(7+x)=88-64
3(7+x)=24
7+x=24:3
7+x=8
x=8-7
x=1
Vậy x=1
