Answer:
Step-by-step explanation:
okay so 2a-15=-1
step 1: Find 2a
2a=-1+15=14.
2a=14
Step : Find a
a=14/2
a=7.
Hope that helps :)
You have to isolate the a. Add fifteen to both sides of the equation, so it’s
2a=15-1
Then subtract 15 and 1, so then the quantity is 14
2a=14
Then divide 2 by both sides, and the answer is
a=7
