Answer:
y = -51
Step-by-step explanation:
y - (-10) = -41
Subtracting a negative number: - (-10) is the same as just adding a positive number + 10, so we'll use this to simplify the expression.
y + 10 = -41
Now, we can subtract 10 from both sides of the equation in order to isolate y.
10 - 10 = 0
-41 - 10 = -51
This means the equation is now:
y = -51
Let's check this answer:
Input -51 as y:
-51 - (-10) = -41
-41 = -41
It works!
This means y = -51 is the answer!

Multiply both sides by 3 and get 2x - 20 = 6x
Then subtract 2x from both sides and get
-20 = 4x. Divide both sides by 4 and then get x = -5
Y = 3x
Proof:
3(1) = 3
3(3) = 9
5. 9(3) = 27
6. 27(3) = 81
7. 81(3) = 243
The 7th term is 243.
