The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
If you mean 3c = 214, then c = 68
An equation where c = -86
-8c+1 = -3 -8c = -3-1 -8c = -4 Divide both sides by -8 in order to find the value of c remembering that a minus number divided into minus number is equal to a plus number: c = 1/2
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
-11
-3
24/3=8
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
17
Because there is no way to define the divisors, the equations cannot be evaluated.
-14 + c + 6 = -5-14 + c = -5 minus 6-14 + c = -11c = -11 minus -14c = -11 plus 14c = 3
four a = 1 c = 3 a + c = 1 + 3 = 4
If you mean 3c = 214, then c = 68
An equation where c = -86
a+b = 17a+c = 36 ----> c = 36 - ab+c = 25 ----> c = 25 - bSo since both are c, we say36 - a = 25 -bFrom this : 11 = a - bLook at 1st eqn: a + b = 17Now we have: a - b = 11 ----> a = 11 + bSo we can substitute that into a + b = 17 to make:(11 + b) + b = 1711 + 2b = 17So b = 3If b = 3, then a + 3 = 17 , so a = 14, 3 + c = 25, so c = 22So a=14, b=3, c=22, so a+b+c = 14+3+22 = 39
b divided by 2
