- 5x-3y=11---(1)
- 3x+4y=4---(2)
(1)×3 and (2)×5
- 15x-9y=33-(3)
- 15x+20y=20-(4)
Subtract both
- Put in eq(1)
Can anybody answer this correctly thank you

Given:
The vertices of a triangle are R(3, 7), S(-5, -2), and T(3, -5).
To find:
The vertices of the triangle after a reflection over x = -3 and plot the triangle and its image on the graph.
Solution:
If a figure reflected across the line x=a, then
The triangle after a reflection over x = -3. So, the rule of reflection is
The vertices of triangle after reflection are
Similarly,
And,
Therefore, the vertices of triangle after reflection over x=-3 are R'(-9,7), S'(-1,-2) and T'(-3,-5).
