4c+2 = 3c+9 4c-3c = 9-2 c = 7
3c-d
3c+6=18 3c+6-6=18-6 3c=12 3c÷3=12÷3 c=4
6c.
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
9c is.
The like terms are sums of b terms and c terms separately 5c+2c+3c+4b 5c +2c + 4b + 3c => 10c + 4b
That's not even a question. It's only a statement that says that some number is equal to itself.
4 + 3c = 2c + 2Subtract 4 from each side:3c = 2c - 2Subtract 2c from each side:c = -2
It is 7 - 8c.
Transitive property of equality
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
