Question

What is the value of a in the equation a = 2 + 3a + 10?

Answer 1

like a first step add the 10 and 2

Answer 2

10+2 = ?

Answer 3

you would change the equation to \(a=(3a)+(2+10)\)
Then combine like terms
which is adding 2 and 10.

Answer 4

12

Answer 5

yes so \(a=3a+12\)
so do you know the second step?

Answer 6

15a?

Answer 7

? no

Answer 8

Answer 9

the next step is to subtract \(3a\) from both sides.

Supie is right because if you get only one side of the equation then you will get a wrong answer.

stop giving direct answers

Answer 20

\(\color{#0cbb34}{\text{Originally Posted by}}\) @supie
a = 2 + `3a` + 10
\(\color{#0cbb34}{\text{End of Quote}}\)
a-a = 12 +3a-a

0 = 12 +2a

-12 = 12 -12 +2a

-12 = 2a

-12/2 = a

a = -6

these is what i ve said above
