Tìm x
A) 8,75×X+1,25×X=20
B)68,25-X=6,45×3,8
tìm x
A>x-4,5=4,94:2,6
B>68,25-x=6,45 nhân 3,8
a, x-4,5=4,94:2,6
x-4,5=1,9
x=1,9+4,5
x=6,4
Vậy x=6,4
b,68,25-x=6,45.3,8
68,25-x=24,51
x=68,25-24,51
x=43,74
Vậy x=43,74
Tìm X :
- 8,75 × x + 1,25 × x = 20
tham khảo
8,75 * x + 1,25 * x = 20
<=>10*x=20
<=>x=20 : 10
<=> x=2
\(-8,75\times x+1,25\times x=20\)
\(x\times\left(-8,75+1,25\right)=20\)
\(x\times-7,5=20\)
\(x=20\div\left(-7,5\right)\)
\(x=-2.6\)
