x = 8, y = 0
y=x-4
y=-x+2
We substitute y=x-4 into the y for y=-
x+2, and we get:
x-4 = -
x+2
+x +
x
x -4 = 2
+4 +4
x = 6
(4)x = 6 (4)
The 4's cross out and we get:
3x = 24
/3 /3
x=8
Not we substitute x(8) into one of our original equations: y=x-4
y=x-4
y=(8)-4
y=4-4
y-0
We get our final answer: (8,0)
Hope that helps!
Answer:
The number of sundaes sold are 36.
Step-by-step explanation:
<em>The cost of each sundae is $2 and the cost of each banana splits is $3.</em>
<em>The number of sundae sold be "x" and banana split be "y".</em>
Thus, the total amount spent is,
=
The total amount spent is given to be $156. Thus,
156 =
It is also given that, the shop sold 8 more sundaes than banana splits. In equation form,
,
Inserting this value of y in above equation, we get,
156 = =
Thus, x = 36 = number of sundae sold.
