Answer:
a
Step-by-step explanation:
Given
y - 3 = (x + 6)
Multiply through by 2 to clear the fraction
2y - 6 = x + 6 ( subtract 2y from both sides )
- 6 = x - 2y + 6 ( subtract 6 from both sides )
- 12 = x - 2y, that is
x - 2y = - 12 → a

Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be and price of 1 toast be
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write
<u>"$.90 for one egg and one piece of toast":</u>
We can write
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:
Now using the value of e (0.6) and putting it back in the first equation, we will get t:
Hence, 1 toast costs $0.30 and 1 egg cost $0.60
