Ta có
\(\left(3x-4\right):4=8\)
\(\Rightarrow3x-4=32\)
\(\Rightarrow3x=36\)
\(\Rightarrow x=12\)
ta có:
(3X - 8):4=7
(3X - 8) = 7.4
(3X - 8) = 28
3X = 28 + 8
3X = 36
X = 36 : 3
X = 12
(3x-8) :4 =7
(3x-8) = 7.4
(3x-8) =28
3x=28 + 8
3x = 36
x=36:3
x =12
ta co:
(x.3-8):4=7
=> x.3-8=7.4
=> x.3=28+8
=> x=36:3
=> x=12
(3x - 4) : 4 = 8
3x - 4 = 32
3x = 36
x = 12
