5x+3y=-5 9x + 3y = ?
Tyler and Han are trying to solve this system by substitution:
Tyler's first step is to isolate x in the first equation to get x =
-5 - 3y. Han's first step is to isolate 3y in the first equation
Explain why both first steps can be used to solve the system and will yield the same solution.

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
