If: -110 = -4c-6c Then: c = 11
It is an equation and the value of c works out as 8
c = 6 and d = 7
Well the c stands for a number. So it means four times what plus three equals eleven? Or you can subtract the three from the eleven then divide that number by four. That's how to solve the problem. Sorry, I won't give you the answer though because you have to figure it out yourself if it's for school or something like that. 4c+3=11 .....-3.. -3 ...4c= 8 ..../4 /4 ________ ....c= ?
1 and 3/4
