Answer:
c = 9
Step-by-step explanation:
First we need to substitute in our known values:
2 ((4X5) + 5c + 4c) = 202
Next we can do the inner multiplication and combine our like terms:
2( 20 + 9c) = 202
Now we distribute the 2:
40 + 18c = 202
Subtract 40 from both sides:
18c = 162
Lastly, divide both sides by 18 to get:
c = 9
Check our work:
2 ((4X5) + (5X9) + (9X4)) = 202
2(20 + 45 + 36 ) = 202
2(101) = 202
202 = 202
