\(88-3\left(7+x\right)=64\)

\(\Rightarrow-3\left(7+x\right)=64-88\)

\(\Rightarrow7+x=\frac{-24}{-3}=8\)

\(\Rightarrow x=8-7=1\)

Tìm x biết :88-3(7+ x)bằng 64

bai giai:

7+x=8

x=8-7

x=1

a) \(88-3\cdot\left(7+x\right)=64\)

\(3\cdot\left(7+x\right)=88-64=24\)

\(7+x=\frac{24}{3}=8\)

\(x=8-7=1\)

b) \(\left[\left(x+32\right)-17\right]\cdot2=42\)

\(\left(x+32\right)-17=\frac{42}{2}=21\)

\(x+32=21+17=38\)

\(x=38-32=6\)

c) \(\left[\left(x^2+54\right)-32\right]:2=61\)

\(\left(x^2+54\right)-32=61\cdot2=122\)

\(x^2+54=122+32=154\)

\(x^2=154-54=100\)

\(\Rightarrow x=\sqrt{100}=10\)

a) \(88-3.\left(7+x\right)=64\)

( 7.x - 15 ) : 3 = 2

7.x - 15 = 6

7.x = 6 + 15

7.x = 21

  x = 3

không biết vì chưa học

88 - 3 ( 7 + x ) = 64

3 ( 7 + x ) = 88 - 64

3 ( 7 + x ) = 24

7 + x = 8

      x = 1

(7.x -15):3=2

x=42-37

x=5

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

dấu . là nhân nhé

\(88-\left(7+y\right)\cdot3=64\)

\(\Rightarrow\left(7+y\right)\cdot3=88-64\)

\(\Rightarrow\left(7+y\right)\cdot3=24\)

\(\Rightarrow7+y=24:3\)

\(\Rightarrow7+y=8\)

\(\Rightarrow y=8-7\)

\(\Rightarrow y=1\)

=>(y+7)*3=24

=>y+7=8

=>y=1

a)88-3(7+x)=64                                  

=>3(7+x)=88-64

=>3(7+x)=24

=>7+x=24:3

=>7+x=8

=>x=8-7=1

tick 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

a)131.x-941=32
131x=32+941=973
x=973:131
  =973/131
b.88-(7+x).3=64
(7+x).3=88-64=24
7+x=24:3=8
x=8-7
x=1
c)51+(26-3x):5=55
(26-3x):5=55-51=4
26-3x=4.5=20
2x=26-20=6
x=6:3=2

a) 131 . x - 941 = 32

     131 . x         = 32 + 941

      131 . x        = 973

               x        = 973 : 131

               x        = 973/131

27x332+68x27+73x332+68x75=332x(27+73)+68x(27+75)

                                             = 332x100+68x102

                                             = 33200+6936=10136
