X=4.2
For the second equation, y=4x-25. Then you plug that into the first equation, which would form: 2x+2(4x-25)=17. Simplify. 2x+8x-25=17. 10x=42. x=4.2

Answer:
x=8
Step-by-step explanation:
3(x+4)=36
Divide each side by 3
3/3 (x+4)=36/3
x+4 = 12
Subtract 4 from each side
x+4-4 = 12-4
x = 8
Answer:
5 cats
Step-by-step explanation:
d/c = 5/1
d = 25 Substitute in the proportion
25/c = 5/1 Multiply both sides by c
25 = 5c/1
25 = 5c Divide each side by 5
c = 5
There are five cats.
