Answer:
Step-by-step explanation:
Let
x-----> amount of pounds of chocolate worth $1.5
we know that
1) 8y + 9 2) 2n + 4 3) 3d + 5h
rearrange the equations and combine like terms. combine the terms with the same variables and add / subtract them.
for example number 1:
9y - 11 + 20 - y
is the same thing as
<em>9y - y</em> <u>+ 20 - 11</u>
and now you can easily combine them:
<em>8y</em> + <u>9</u>
i hope this helps!
