x+y=45
x=y+7
Use substitution...
Plug y+7 into the first equation. You get (y+7)+y=45. Next combine the like terms. 2y+7=45. Subtract 7 from both sides and you get 38. Divide 2 on both sides to get y alone and you get 19. Since there are more cats than dogs, this is the amount of dogs. Add 19+7 since there are 7 more cats than dogs and you get 26 cats. Therefore there is 19 dogs and 26 cats.
Step-by-step explanation:
Katie's deposits are positive: 23.87, 41.03, and 61.33.
Her withdrawals are negative: -4.34 -21.11, -8.78.
Sorted from least to greatest (most negative is least, most positive is greatest):
-21.11, -8.78, -4.34, 23.87, 41.03, 61.33
Katie started with $128. Add to it all the deposits and withdrawals:
128 − 21.11 − 8.78 − 4.34 + 23.87 + 41.03 + 61.33 = 220
