If 8c = 60, then c = 60/8 = 7.5.
8c + 24 + 23 = 71subtract 47 from each side, 8c = 24divide each side by 8, c = 3
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
-8c + 1 = -3 => -8c = -3 + 1 => -8c = -2 => c = -2/(-8) => c = 1/4 = 0.25

If 8c = 60, then c = 60/8 = 7.5.
8c
-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
8c + 24 + 23 = 71subtract 47 from each side, 8c = 24divide each side by 8, c = 3
2. c2 + c2 + 8 = 8c 2c2 - 8c + 8 = 0 c2 - 4c + 4 = 0 (c - 2)(c - 2) = 0 (c - 2)2 = 0 c - 2 = 0 c = 2
It is: 6-11+5-8c+9c = c
(8a)(8b) = (8c)/(8d); multiply both sides by 8d to obtain (8a)(8b)(8d) = (8c); divide both sides by 8 to obtain (8a)(8b)d = c; divide both sides by (8a)(8b) to obtain d = c/[(8c)(8b)].
divide 120 by 8 and that is C
-15 = 8c - 15Add 15 to each side:0 = 8cDivide each side by 8:c = 0
