144 9+7 = 16 and 9*16 = 144
4c+2 = 3c+9 4c-3c = 9-2 c = 7
The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
It is 7 - 8c.
It is 7 - 8c.
Question 3C: Four minus seven equals negative two.
It's a simple linear equation in one unknown.If you'd like to know what value of 'c' makes it true, you can find it like this:7 = -3c - 2Add 3c to each side:7 + 3c = -2Subtract 7 from each side:3c = -9Divide each side by 3:c = -3
3c-7 = -4
Multiplying out the brackets it is: 7a+21-ac-3c
93 + 68 + 7 is an arithmetic expression. In itself, it has no properties.
It equals 24.
