x = ?

please help

Answer 1

1/3 (9x - 6) = 2x + 3 --- distribute through the parenthesis
3x - 2 = 2x + 3 -- subtract 2x from both sides
3x - 2x - 2 = 3 -- add 2 to both sides
3x - 2x = 3 + 2 -- combine like terms
x = 5

check.
1/3(9(5) - 6) = 2(5) + 3
1/3( 45 - 6) = 10 + 3
1/3 (39) = 13
13 = 13 (correct)

so x = 5
