⚠️⚠️HELP WHATS THE BLANK it’s not change or conservation:⚠️⚠️ energy cannot be created or destroyed it [BLANK] from one form to another but the total amount of energy stays the same

transferred

Explanation:

"Energy cannot be created or destroyed, it can be transferred from one form to another..."

sorry if it's not right!! Most of the time the conservation law is changed I don't know what's up with that maybe it's your specific book.

[changes]

Explanation:

energy cannot be created or destroyed it changes from one form to another but the total amount of energy stays the same

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
