We are given this equation a+5=11
here 5 is in addition on the left side
so in order to eliminate it , we perform opposite operation of addition on the right side.
opposite operation of addition is subtraction.
so subtracting 5 on the right side , we get
a=11-5
a=6
so this is how a=6 is the answer
a + 5 = 11
You need to isolate the variable by subtracting from both sides
a + 5 - 5 = 11 - 5a = 6
The Addition/Subtraction Property of Equality states that if you add or subtract the same number to both sides of an equation the two sides still remain equal.
