Answer - 30x-18
Explanation: you multiply six by all the numbers in parentheses, and since there are no like terms, you leave it as 30x-18. Hope this helps
Answer:
The larger number = 116
Step-by-step explanation:
Let the smaller number = x
Given that one number is 78 more than another, so
The larger number = x+78
Given that if we add 12 to the smaller number, the result is 50, so

subtract 12 from both sides

Simplify

Therefore,
- The larger number = x+78 = 38+78 = 116
Thus, the larger number = 116
I used the quadratic formula and got x= 4, -6
