Follow the description and the question exactly how they are written.

M Mia
K Kristina
system%28M=-4%2B3K%2CM%2B6=7%2B2%28K%2B6%29%29

and question asks for M+6.
Handle the rest any way you know how; basically simple algebra steps.
-
M%2B6=7%2B2K%2B12
M=2K%2B12%2B1
M=2K%2B13
-
M=3K-4=2K%2B13
K=13%2B4
highlight_green%28K=17%29
-
M%2B6=2K%2B19bysubstitution:
M%2B6=34%2B19
highlight%28M%2B6=highlight%2853%29%29
