25a+ 15c = 7200

anonymous · Answer

solve system by substitution or elimination...are you familiar with how to do that?

anonymous · Answer

a=400-c
25(400-c)+15c = 7200
10000-25c+15c=7200
10000-10c=7200
-10c=-2800
c=280
a=400-280=120

check 120+280=400
25(120)+15(280)=7200
3000+4200=7200
7200=7200
