My answers were
d=2.6
c=1.45
4c+2d= 11
3.5d=41-22c
Bring 22c to the left hand side . The sign changes from negative to positive.
4c+2d=11
22c+3.5d=41
Multiply the first equation by 22. Multiply the second equation by 4 . I am eliminating c first
88c + 44d= 242
88c +14d=164
Then minus for the two questions.
30d= 78f
d= 78 /30
Then divide the two numbers by 6
d= 13/5
d=2.6
Next find c
The next step is substitution into any of the two equations.
4c +2d=11
4c+2( 2.6) =11
4c +5.2=11
4c = 5.8
c =1.45
Final answer: (1.45 , 2.6)
