So I have the given problem a = 2 + 3a + 6? I want to make sure what i wrote is correct I had four options
I choose negative four and here's my work I am just slightly confused because I have always had a given value on the other side of the equation never just a letter.
a = 2 + 3a + 6? first I gathered my like terms
a = 2 + 3a + 6 then I added the numbers
= 8 + 2a then I carried over the 8 to the other side making sure to be subtracting it from nothing resulting negative 8
and 2 goes into - 8 -4 times so I got -4 for A in the equation.
a = 2 + 3a + 6
subtract 3a from both sides —» a –3a = 2 + 6
–2a = 8
divide both sides by –2 a = –4
You did it right. It's just my personal preference to have the unknown on the left hand side.
