3x10=(2x10)+(1x_)

What is the factor

Comments

Was x meant as a symbol for multiplication or did you mean to write x as a factor with the exponent of 10 (x^10)?

3*10 = 2*10 + 1*10
 
Just like 3a = 2a + 1a

3x10=(2x10)+(1x?)
The first step is to multiply to solve inside the parenthesis
 
3x10=(2x10)+(1x?)
  30 =  (20) + (1x?)
 
Next subtract 20 from both sides
 
30-20=20-20+(1x?)
 
10=1x?
 
Any number multiplied by 1 is itself therefore the answer is 10
 
?=10

Hi Shannon;
3x10=(2x10)+(1x_)
What I believe this is...
 
3x10=2x10+1x?
?=10
3x10=2x10+1x10
 
x10 is a single unit.
It is as single as x.
Just as 2x+x=3x, so too does 2x10+1x10=3x10
