1.) add 9 and 5 which is 14-6x
X = x4
And
Y = x2
Because of the fact the cows have 4 legs and chickens have 2
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
Answer:
291
Step-by-step explanation:
2x2x2=8
8x2=16
5x5x11=275
275+16=291
