Video Transcript

for this exercise. We are told to use antimatter to solve the London increase. And we're giving it to questions which are expert. My wife screwed equals nine and I was sad Conclusion why? You can see, I think the easiest way to solve this equation is to use the substitution that since our second equation already tells us that why you called three. So that's your substitution. We want to substitute our second equation into first equation and substitute why into y screwed. So we really have expert miners. Three screwed equals nine with sequels and screw minus nine because nine. So our expert calls 18. Therefore, our ants, of course, plus minus sterile room 18. So we know that our X equals plus minus curved 18 and why was already given you two or three? So our final solution Saturdays plus minus start of 18 and see where it is his ex and lie therefore days is our final solution
