4c+2 = 3c+9 4c-3c = 9-2 c = 7
When c = -3 then 4c + 5c - 2 = [4 x -3] + [5 x -3] - 2 = -12 +(-15) - 2 = -12 -15 -2 = -29
17-3= 4c+3c c=2
4c-7 = 2c+11 4c-2c = 11+7 2c = 18 c = 9
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
It is an equation and the value of c works out as 8
4c+2 = 3c+9 4c-3c = 9-2 c = 7
When c = -3 then 4c + 5c - 2 = [4 x -3] + [5 x -3] - 2 = -12 +(-15) - 2 = -12 -15 -2 = -29
17-3= 4c+3c c=2
4c-7 = 2c+11 4c-2c = 11+7 2c = 18 c = 9
48c + 408
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
8c + 5 = 4c - 11Subtract 4c from each side:4c + 5 = -11Subtract 5 from each side:4c = -16Divide each side by 4:c = -4
c = 6 and d = 7

4c = 12 c = 3
2a + 2b = 26 2b + c = 22 ===> b = 11 - c/2 4c + 2b = 46 ===> b = 23 - 2c From the 2nd and 3rd equations: 11 - c/2 = 23 - 2c 22 - c = 46 - 4c 22 - 46 = -4c + c ===> -24 = -3c ===> c = 8 Substitute c=8 into the 3rd equation: b = 23 - 16 = 7 Substitute b=7 into the 1st equation: 2a + 14 = 26 2a = 12 ===> a = 6
