Question

Solve each linear system in 2D space:[x,y,z]=[16,1] + s[5,1], [x,y,z]=[-7,12] + t[-7,3]I have solved part of this question: x=16+5s, y=1+s x=-7-7t, y=12+3t. Those equations are rearranged to: 16+5s=-7-7t and 1+s=12+3t, I rearranged this equation to: s=11+3t and subbed it in to the other equation:16+5(11+3t)=-7-7t which equals 16+55=15t=-7-7t, and is then rearranged to equal 77+7=-7t-15t which equals 84=-22t and now t= 84/-22 and finally t=42/11 What do I do now?

Answer 1

find s

Answer 2

you have to solve it in 2D so u just make 4 equation 2 in x and 2 in y solve them and get 2 equations finally in s and t you solve it and get t


NOw find s and then find x,y as initially u have to find 2D coordinates i.e[x,y] of [x,y,z]:)

Answer 3

Thank you!

Answer 4

anytime and mention not:)
