Answer:
5 - 8z + y + 10
Explanation:
Let's first simply the question
5 - 8z + y + 7 + 3
then we have to just use the operations to solve the sum
5 - 8z + y + 7 + 3 = 8z + y + 10
Answer = 5 - 8z + y + 10
Note: If the equation doesn't have the same pro numeral it can't be added or subtracted by a number that has different pro numeral, unless we are multiplying.
Hope you understand
