The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.

The expression for the total amount of apples is 29x
<em><u>Solution:</u></em>
Given that,
Sarah has 12 bags of apples
Mikaela has 17 bags of apples
Each bag has the same amount of apples inside
Let "x" be the number of apples in each bag
Then,
Sarah has 12x apples
Mikaela has 17x apples
<em><u>Wrie an expression for the total amount of apples</u></em>
Total amount of apples = 12x + 17x
<em><u>Then simplify it using the distributive property to create an equivalent expression</u></em>
By distributive property,
a(b + c) = ab + bc
Therefore,

Thus expression for the total amount of apples is 29x
