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.

Rasek [7]
Since there are 26 students in Mr. Carson's class, and each kid gets 3 pencils, that means we will multiply 26 and 3, in which we get 78. Now, since boxes of pencils only contain a dozen, which is 12 pencils, we will divide 78 by twelve, in which we get 6.5 boxes. You can't buy half a box, so he will need 7 boxes, since having 6 boxes means that you don't have enough pencils.

Hope this helps!
