x + x + x + x + 45 = 127 - 58
x . 4 + 45 = 69
x.4 = 69 - 45 = 24
x = 24 : 4
x = 6
\(x+x+x+x+45=127-58\)
\(x+x+x+x+45=69\)
\(x+x+x+x=69-45\)
\(4\cdot x=24\)
\(x=6\)
\(x+x+x+x+45=127-58\)
\(x.4+45=69\)
\(x.4=69-45\)
\(x.4=24\)
\(x=6\)
x + x + x + x + 45 = 127 - 58
\(x^4\)+ 45 = 69
\(x^4\) = 69 - 45
\(x^4\) = 24
x + x + x + x + 45 = 127 - 58
x . 4 + 45 = 69
x . 4 = 69 - 45
x . 4 = 24
x = 24 : 4
x = 6
x + x + x + x + 45 = 127 - 58
4x + 45 = 69
4x = 69 - 45
x = 24 : 4
x = 6
\(x+x+x+x+45=127-58\)
\(\Rightarrow x\times4+45=69\)
\(\Rightarrow x\times4=69-45\)
\(\Rightarrow x\times4=24\)
\(\Rightarrow x=24:4\)
\(\Rightarrow x=6\)
Vậy \(x=6\)
Học tốt !
X + X + X + X + 45 = 127 - 58
X + X + X + X + 45 = 69
( X x 4 ) + 45 = 69
X x 4 = 69 - 45
X x 4 = 24
X = 24 : 4
X = 6
X + X + X + X + 45 = 127 - 58
X x 4 + 45 = 69
X x 4 = 69 - 45
X x 4 = 24
X = 24 : 4
X = 6 .
Tk nha!!!!
x + x + x + x + 45 = 127 - 58
=> x + x + x + x + 45 = 69
=> x + x + x + x = 69 - 45
=> x + x + x + x = 24
=> x = 24 : 4
=> x = 6
chia 4 là vì có 4 chữ x nhé
x + x + x + x + 45 = 127 - 58
x × 1 + x × 1 + x × 1 + x × 1 + 45 = 69
x × ( 1 + 1 + 1 + 1 ) + 45 = 69
x × 4 + 45 = 69
x × 4 = 69 - 45
x × 4 = 24
x = 24 : 4
x = 6
Vậy x = 6
x + x + x + x + 45 = 127 - 58
x + x + x + x + 45 = 69
x + x + x + x = 69 - 45
4x = 24
=> x = 6
x + x + x + x + 45 = 127 - 58
<=> 4x + 45 = 69
<=> 4x = 69 - 45
<=> 4x = 24
<=> x = 24 : 4
<=> x = 6
Vậy x=6
x + x + x + x + 45 = 127 - 58
x + x + x + x + 45 = 69
x + x + x + x = 69 - 45
4x = 24
x = 6
hok tốt
x+x+x+x+45=127-58
=x x 4+45=69
x.4=69-45
x.4=24
x=24:4
x=6
\(x+x+x+x+45=127-58\)
\(x+x+x+x+45=69\)
\(x\cdot4+45=69\)
\(x\cdot4=69-45\)
\(x\cdot4=24\)
\(x=24\text{ : }4\)
\(x=6\)
