Answer:
Option a=$6.37 is correct
The value of the variable is the solution of the given equation is a=$6.37
Explanation:
Given equation is a+$5.92=$12.29
To find the value of the variable is the solution of the given equation :
a+$5.92=$12.29
Subracting the above equation by $12.29 on both sides we get
a+$5.92-$12.29=$12.29-$12.29 ( Subtraction property of equality)
a-$6.37=0
Now add $6.37 on both sides we get
a-$6.37+$6.37=0+$6.37 ( Addition property of equality)
a-0=$6.37
Therefore a=$6.37
Therefore option a=$6.37 is correct
