In this lesson, we will learn how to geometrically visualize a system of equations and express it as a matrix equation.
Q1:
Express the following set of simultaneous equations as a matrix equation: 7𝑥−3𝑦+6𝑧=5,5𝑥−2𝑦+2𝑧=11,2𝑥−3𝑦+8𝑧=10.
Q2:
Express the set of simultaneous equations 3𝑥=12+5𝑦+2𝑧,𝑥−5𝑦=21,11𝑥−8𝑦=−10+2𝑧 as a matrix equation.
Q3:
Write down the set of simultaneous equations that could be solved using the matrix equation 224−1−1−1256𝑝𝑞𝑟=41410.
