And I will step you through one of these current ones:
1/5 x - 2 = 4 First thing to do is get your similar terms on the same side of the equation; and what you do to one side of the equation you must do to both sides; so,
1/5 x - 2 + 2 = 4 + 2; and, 1/5 x = 6. Now, multiply both sides by 5 to isolate your unknown quantity x;
5 (1/5 x) = 5 x 6 = 30. And so, x = 30, which is your solution.
You can check your answer for accuracy simply by plugging 30 in for x in your original equation, like this:
1/5 (30) - 2 = 4 30/5 - 2 = 4 6 - 2 = 4
Now can you ask a family member or a teacher to help make sure you understand how to get to these solutions? It is very important that you understand it yourself, rather than just taking down the answers.
Double sided equations are calculated by collecting all like terms to one side of the equation and letting other figures remain on the opposite side. This makes it possible to evaluate the value of the unknown value.
