I NEED HELP PLEASE!<br><br> If you can help me with this you amazing!<br><br> Thank you
krek1111 [17]

Answer:

a=-3

Step-by-step explanation:

we have

a-2=\frac{3+6a}{3}

Solve for a

That means ----> Isolate the variable a

Factor 3 in the numerator right side

a-2=\frac{3(1+2a)}{3}

Simplify right side

a-2=1+2a

subtract a both sides

a-2-a=1+2a-a

-2=1+a

subtract 1 both sides

-2-1=1+a-1

-3=a

Rewrite

a=-3
