Answer 1

You need to go through several steps aimed at isolating terms with the variable "a" in them on the left side of an equation and everything else on the right side.

Start by multiplying out 6(a+3) and -3(1-2a). Please show all your work.

Answer 2

PEMDAS :D
I love PEMDAS...
Mkay, so we're solving for the variable, which is 'a'

P-parentheses.
There's absolutely nothing that we can simplify inside of the parentheses So we move on to-
E-exponents
there are no exponents so we move on to;
M/D -multiplication and division!
6(a + 3)
and
-3(1 - 2a)
