Answer:
a = -3
Step-by-step explanation:
-2(a-3)=12
distribute the -2 to the terms in the paranthesis
-2a + 6 = 12
minus 6 both sides
-2a = 6
divide -2 both sides to isolate a
a = -3

Answer:
10
Step-by-step explanation:
Begin with writing down your problem. For example, you want to divide 1284 by 14.
Decide on which of the numbers is the dividend, and which is the divisor. The dividend is the number that the operation is performed on - in this case, 1284. The divisor is the number that actually "does the work" - in this case, 14.
Perform the division - you can use any calculator you want. You will get a result that most probably is not an integer - in this example, 91.7142857.
Round this number down. In our example, you will get 92.
Multiply the number you obtained in the previous step by the divisor. In our case, 92 * 14 = 1294.
Subtract the number from the previous step from your dividend to get the remainder. 1284 - 1294 = 10.
