Question

Consider the following pair of equations: y = −2x 8 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

Answer 1

If so y= -2x and 8y=x-1...

solution:

$y=-2x \\ \\ 8y=x-1 \Rightarrow \\ \\ 8.(-2x)=x-1 \Rightarrow \\ \\ -16x=x-1 \Rightarrow \\ \\ 17x=1 \Rightarrow \\ \\ x=\dfrac{1}{17}$

Answer 2
