Tìm y:
a) y x 2,8 + 5,2 x y = 48
b) y x 12,25 – y + y x 2,75 = 1050
\(a,y\times2,8+5,2\times y=48\\ y\times\left(2,8+5,2\right)=48\\ y\times8=48\\ y=\dfrac{48}{8}=6\\ ---\\ b,y\times12,25-y+y\times2,75=1050\\ y\times\left(12,25-1+2,75\right)=1050\\ y\times14=1050\\ y=\dfrac{1050}{14}=75\)
a: \(y\cdot2,8+y\cdot5,2=48\)
=>\(y\left(2,8+5,2\right)=48\)
=>\(8y=48\)
=>\(y=\dfrac{48}{8}=6\)
b: \(y\cdot12,25-y+y\cdot2,75=1050\)
=>\(y\left(12,25-1+2,75\right)=1050\)

X x 12,25 - X + X x 2,75 = 1050
x * 12,25 - x + x * 2,75 = 1050
\(x=75\)
học tốt
nếu bn ko hiểu thì nhắn mik mik giải ra chi tiết cho nhé
x * 12,25 - x + x * 2,75 = 1050
= x * ( 12,25 - 1 + 2,75 ) = 1050
= x * 14 = 1050
= x = 1050 : 14
x = 75
X x 12,25 - X + X x 2,75 = 1050
\(\Leftrightarrow Xx\left(12,25-1+2,75\right)=1050\)
\(\Leftrightarrow14xX=1050\)
\(\Leftrightarrow X=75\)
X x (12,25-1+2,75)=1050
X x 14 = 1050
X=1050/14
X=75
x . 12 ,25 - x + x . 2, 75 = 1050
<=> x . ( 12,25 - 1 + 2,75 ) = 1050
<=> x . 14 = 1050
<=> x = 1050 : 14
<=> x = 75
Vậy x = 75
Tìm x biết
2/3*x+3/4=3
x*12,25-x+x*2,75=1050
c) x.2,8 + x.5,2 = 48 d) x.12,25 – x + x.2,75 = 1050
c) x . (2,8 + 5,2) = 48 x . 8 = 48 x = 48 : 8 x = 6 d) x . (12,25 - 1 _ 2,75) = 1050 x . 14 = 1050 x = 1050 : 14 = 75
c) \(x\times2,8+x\times5,2=48\)
\(x\times\left(2,8+5,2\right)=48\)
\(x\times8=48\)
\(x=6\)
d) \(x\times12,25-x+x\times2,75=1050\)
\(x\times\left(12,25-1+2,75\right)=1050\\ x\times14=1050\\ x=75\)
Tìm x :
a. x+3,5=4,72
b. x.18:4=72.0,25
c. x.12,25-x+x.2,75=1050
a) x + 3,5 = 4,72
x = 4,72 - 3,5
x = 1,22
b) x . 18 : 4 = 72 . 0,25
x . 18 : 4 = 18
x . 4,5 = 18
x = 18 : 4,5
x = 4
c) x . 12,25 - x + x . 2,75 = 1050
x . 12,25 - x x 1 + x . 2,75 = 1050
x . ( 12,25 - 1 + 2,75 ) = 1050
x . 14 = 1050
x = 1050 : 14
x = 75
Tìm x:
x . 12,25 - x + x . 2,75=1050
x . 12,25 - x + x . 2,75=1050
x.(12,25-1+2,75)=1050
x.14=1050
x=75
Vậy x=75
Tìm X
X x 12,25- X+X x 2,75=1050
ai làm đầy đủ mình tích cho
x*(12.25-1+2.75)=1050
x*14=1050
x=1050:14
x=75
\(x.12,25-x+x.2,75=1050\)
\(\Leftrightarrow x.12,25-x.1+x.2,75=1050\)
\(\Leftrightarrow x\left(12,25-1+2,75\right)=1050\)
\(\Leftrightarrow x14=1050\)
\(\Leftrightarrow x=1050:14=75\)
