Tìm x biết:
x/36 = 76/57
Tìm x,biết: x/36 = 76/57
\(\dfrac{x}{36}=\dfrac{76}{57}\)
\(\dfrac{x}{36}=\dfrac{4}{3}\)
\(\dfrac{x}{36}=\dfrac{48}{36}\)
\(\Rightarrow x=48\)
tìm x biết x/36 = 76/57
giải chi tiết ra nhe
\(\dfrac{x}{36}=\dfrac{76}{57}\)
=> \(\dfrac{x}{36}=\dfrac{4}{3}\)
=> \(\dfrac{x}{36}=\dfrac{48}{36}\)
=> x = 48
x/36 = 76/57
Tìm x
X/36 = 76/57
=> X = 36x76/57
=> X = 48
tìm x : x/36=76/57
Tìm x : x /36 = 76/57
Tìm x, biết : x/36 = 76/57
`x/36=76/57`
`57xx x=76xx36`
`57 xx x=2736`
`x=2736:57`
`x=48`
Tìm x, biết:

Tìm x, biết:
a ) 4 7 . x + 2 3 = − 1 5 b ) 2 9 − 7 8 . x = 1 ; c ) 4 5 + 7 6 : x = 1 6 d ) 5 7 : x − 1 = 2 3
a ) x = − 91 60 . b ) x = − 8 9 . c ) x = 35 19 . d ) x = 3 7 .
Tìm x biết :
A) x + 13 = 32 - 76
B) (-15) + x = (-14) - (-57)
\(x+13=32-76\)
\(\Leftrightarrow x+13=-44\)
\(\Leftrightarrow x=-44-13\)
\(\Leftrightarrow x=-57\)
\(-15+x=-14-\left(-57\right)\)
\(\Leftrightarrow-15+x=-14+57\)
\(\Leftrightarrow-15+x=43\)
\(\Leftrightarrow x=43+15=58\)
A) x + 13 = 32 - 76
x + 13= -44
x = (-44) - 13
x = -57
Vậy x = -57
B) (-15) + x = (-14) - (-57)
(-15) + x = (-14) + 57
(-15) + x = 43
x = 43 + (-15)
x = 43 - 15
x = 28
Vậy x = 18
