Answer:
21 is answer
Step-by-step explanation:
Find the value of expression the a3−3a2+5a−7 by substituting a=3.
For this problem, we can move all the X's to one side and all the regular numbers to the other.
7x comes over and become -7x
10 goes over and becomes -10.
5x+7x-7x=-3-10+13+12.
-3-10=-13, which cancels out the positive 13.
-7x+7x=0 which cancels each other out.
Now, 5x=12
Divide each side by 5.
x=2.4 <--- final answer.
