How do enzymes lower activation energy

When an enzyme binds to its substrate, we know it lowers the activation energy of the reaction, allowing it to happen more quickly. ... The enzyme-substrate complex can also lower activation energy by bending substrate molecules in a way that facilitates bond-breaking, helping to reach the transition state.

I hope this helps :D

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
