Question

What is the value of a? -2(a-8)+6a=36

Answer 1

-2(a-8)+6a=36
=>-2a + 16 + 6a = 36
=> 4a = 36 - 16
=> 4a = 20 
=> a = 20 / 4
=> a = 5 ..

Hope it helps !!!!

Answer 2

First we expand the brackets:

-2a + 8 + 6a = 36
4a + 8 = 36

We then need to get the a's onto one side and the numbers onto the other:

4a = 28

We can then divide to get an x by itself:

a = 28/4 = 7
