2.14a +1.b25

c.865

how do I solve this and what are the answers for a. b. and c.

a=0, b=7, c=3

Step-by-step explanation:

Addition

The following addition is shown, where a,b, and c are unknown:

 2.14a

+ 1.b25

  c.865

We'll determine the values of the unknown variables by following the rules of addition.

The last column shows a+5=5. Since a cannot be greater than 9, thus a must be 0.

a = 0

This sum produces no carry.

Now we have 4 + 2 = 6

This is already correct and no variable needs to be calculated

Now we have 1 + b = 8. This leads to b=8-1=7

b = 7

This sum produces no carry.

Finally: 2 + 1 = c. This implies that

c=3

Substituting in the addition:

 2.140

+ 1.725

  3.865

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
