Thus the equation becomes
You want to manipulate this equation, always maintaining the equality, and end with an equation of the form
Thus you want all the terms containing x on one side of the equation so add 3 to both sides. This maintains the equality and produces
You don't want the 2 on the left of the equality so add 2 to both sides
Finally multiply multiply both sides by 1 to get
The first problem I assume is I would multiply both sides by 6 to obtain which becomes
Now continue as in the second equation you sent. Good luck on the test,
The English would be "Solve for X" or "Find X". (That may help make the goal clearer if English is your first language.) Things you are allowed to do:
How you use these: first aim to get rid of parentheses and fractions with other operations "inside". Then try to get all terms with "x" onto one side and all terms without "x" onto the other. Thus:
