Solution

Finding the sum of algebraic expressions
Adding the given algebraic expressions by horizontal method, we get
$(3 x + 11 + 8 z) + (- 6 x + 4 z) = 3 x + 11 + 8 z + (- 6 x) + 4 z = 3 x + (- 6 x) + 8 z + 4 z + 11 = - 3 x + 12 z + 11$
Hence, the sum of given algebraic expressions is $- 3 x + 12 z + 11$ .
