1/2 + X x 3/4 = 2
X x 3/4 = 2 - 1/2
X x 3/4 = 3/2
X = 3/2 : 3/4
X = 1/2
1/2+x*3/4=2
1/2+x=2*4/3
1/2+x=8/3
x=8/3-1/2=16/6-3/6
x=13/6
a) \(x:\frac{1}{2}=4\)
\(x=4\times\frac{1}{2}\)
\(x=2\)
b)\(x\times\frac{3}{5}=15\)
\(x=15:\frac{3}{5}\)
\(x=25\)
a) \(\text{X}\div\frac{1}{2}=4\)
\(\text{X}=4\times\frac{1}{2}\)
\(\text{X}=2\)
b) \(\text{X}\times\frac{3}{5}=15\)
\(\text{X}=15\div\frac{3}{5}\)
\(\text{X}=25\)
X x 3+ X : 4 =26
X x 3 + X x 1/4 = 26
X x ( 3 + 1/4 ) = 26
X x 13/4 = 26
X = 26 : 13/4
X = 8
\(x\) \(\times\) 3 + \(\dfrac{x}{4}\) = 26
\(x\times3+x\times\dfrac{1}{4}\)=26
\(x\times\left(3+\dfrac{1}{4}\right)\) = 26
\(x\times\dfrac{13}{4}\) = 26
\(x=26:\dfrac{13}{4}\)
\(x=8\)
X x 3:8 - 1912 = 7778
X = 7778 + 1912
X = 9690
X =9690 x 8
X = 77520
X = 77520:3
X = 25840
Đáp số : X = 25840
( X x 2 + 3 + 4 + 1 ) = 2130
X x 10 = 2130
X = 2130 : 10
X = 213
Xx2+Xx3+Xx4+X=2130
Xx(2+3+4+1) =2130
Xx10 =2130
X =2130:10
X =213
Xx3+Xx5+Xx7+.......+Xx101= 31200
Xx(3+5+7+.....+101)= 31200
Xx 2600= 31200
X= 12
\(\dfrac{3}{5}x=\dfrac{3}{2}\Leftrightarrow x=\dfrac{3}{2}:\dfrac{3}{5}=\dfrac{5}{2}\)
X x \(\dfrac{3}{5}=2-\dfrac{1}{2}\)
\(X\times\dfrac{3}{5}=\dfrac{3}{2}\)
\(X=\dfrac{3}{5}:\dfrac{3}{2}\)
\(X=\dfrac{2}{5}\)
