"old macdonald had a farm." but on his farm, he only raised pigs and chickens - 48 of them all together. one day, he noticed that the total number of heads and wings was equal to the total number of feet. how many pigs and how many chickens did old macdonald have on his farm?

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
