7a-3=3-2a

I don't know how to solve this question

Get all variables (in this case, "a") on one side by adding "2a" to both. this cancels the "-2a". then, combine like terms. also move "-3" to the other side, by adding "3". finally, divide the "6" and "a" by "9" to get variable alone. therefore, "a = 2/3".

7a-3=3-2a

+2a + 2a

9a-3=3

+3 + 3

9a=6

a=2/3

7a-3=3-2a

9a-3=3 (add 2a to both sides)

9a=6 (add 3 to both sides)

a=6/9 (divide by 9 to both sides)
