[1/2 Digtal analysis] Work:Break 2 into prime factors. Question type: Resolving prime factor Solution: 2=2 *Note: 2 is a prime number. [ 2/2 Equation] Work: Find the solution of equation 10 = 20t-5t . Question type: Equation Solution:Original question:
10
=
20
t
−
5
t
Right side of the equation =
15
t
The equation is transformed into :
10
=
15
t
Transposition :
-
15
t
=
-
10
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
10
=
15
t
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
15
t
=
10
The coefficient of the unknown number is reduced to 1 :
t
=
10
÷
15
=
10

3
This is the solution of the equation.
Convert the result to decimal form :
t
=
0.666667
