Answer:
<h2>cherry pie = 5</h2><h2>lemon pie =10</h2>
Step-by-step explanation:
Step one:
let cherry be x
and lemon be y
the systems of the equation for the solution is given as
4x+y=30-----------1
8x+6y=100------2
Step two:
solve the equation simultaneously by substitution we have
4x+y=30
y=30-4x
put y=30-4x in equation 2
8x+6(30-4x)=100
8x+180-24x=100
8x-24x=100-180
-16x=-80
x=80/16
x=5
put x=4 in y=30-4x
y=30-4(5).
y=30-20
y=10
