How do I solve this problem?
3(3x+6)=4(7x-1)

Answer 1

As a first step, I would "distribute" the 3 on the left side... that means
multiply every term inside the parens by 3

also distribute the 4 on the right side
what do you get ?

Answer 2

9x+18 = 28x-4

Answer 3

yes, now add -9x to both sides, like this
-9x + 9x + 18 = 28x - 9x -4

can you simplify that ?

Answer 4

on the left side you have 9 x's take away 9 x's
on the right side you have 28 x's take away 9 x's

Answer 5

18=19-4

Answer 6

not just 19,
it is 19x (28 x's take away 9 x's leaves 19 x's)
18 = 19x -4

now add +4 to both sides and simplify
what do you get ?

Answer 7

like this
18+4= 19x -4 + 4
