Step 1) Combine like terms/variables.
7y and -2y are similar, combine them.
7+(-2y)=5y
3x has no similar variables, so it stays the same
3 and 6 are similar, without variables, combine them.
3+6=9
The final answer is 5y+3x+9
Answer:
The farmer bought 36 pigs in all.
Step-by-step explanation:
Given that a farmer bought a number of pigs for $ 160, but, however, 8 of them died before he could sell the rest at a profit of 6 per pig, and his total profit was $ 8, to determine how many pigs did he originally buy the following calculation must be performed:
160 + 8 = 168
168/6 = 28
28 + 8 = 36
Thus, the farmer bought 36 pigs in all.
