Are you to combine the answer or are they 2 separate equations you need to solve for y?

Since both equal x, just subsitute them
3y-1=x=-2y+9
3y-1=-2y+9
add 2y to both sides
5y-1=9
add 1 to both sides
5y=10
divide both sides by 5
y=2

sub back into any equation
x=3y-1
x=3(2)-1
x=6-1
x=5

x=5
y=2
(5,2)

M(2,5) is the midpoint of RS. The coordinates of S are (3,9). What are the coordinates of R?

kobusy [5.1K]

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ R(\stackrel{x_1}{x}~,~\stackrel{y_1}{y})\qquad S(\stackrel{x_2}{3}~,~\stackrel{y_2}{9}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{3+x}{2}~~,~~\cfrac{9+y}{2} \right)~~=~~\stackrel{M}{(2~,~5)}\implies \begin{cases} \cfrac{3+x}{2}=2\\[1em] 3+x=4\\ \boxed{x = 1}\\ \cline{1-1} \cfrac{9+y}{2}=5\\[1em] 9+y=10\\ \boxed{y=1} \end{cases}$
