I'm assuming that the 3434 is a typo error. It should be 34.
Marni: 18 + 0.80m
Sharika: 12 + 0.9m
x = Sharika's minutes
x + 34 = Marni's minutes
[18 + 0.80(x+34)] + [12 + 0.90(x)] = 264
18 + 0.80x + 27.2 + 12 + 0.90x = 264
0.80x + 0.90x = 264 - 18 - 27.2 - 12
1.70x = 206.80
x = 206.80/1.70
x = 121.65 or 122
x + 34 = 122 + 34 = 156 minutes.
