Answer: a 15y=18 and c 5y+4=10
Step-by-step explanation:
Answer:
3. 8 degrees/90 minutes
4. 200 miles/3 hours
5. $6/5 pickles
-5 and -9 are the constants, can also be written -14
-8
(x-3y=136) + (18x+3y=288) We collect both processes to make y's disappear
19x=-152
x=-8
21/2 so 10.5.
7÷2/3=21/2=10.5
