What's the answer for the following:i need step by step directions on how to solve them?

Question

my teacher didn't go over on how to solve these kind of problems and i have a test on it. a i need help. please give me helpful answers and not "do your own homewrok" answers. thanks

9x + 2=36
4x= 3+24
5-12x=3

Answer 1

Alrighty-
You move all the numbers to one side-doing the opposite of what it was, and leave numbers with variables (9x) on the opposite side. Then you simplify and solve.

9x + 2 = 36 move the 2 to the other side, and do the opposite
9x = 36 - 2 simplify
9x = 34 solve (do the opposite to the 9 so divide)
x = 34/9
x = 3 7/9

4x = 3 + 24 simplify
4x = 27 solve
x = 27/4
x = 6 3/4


5 - 12x = 3 move the 5 to the other side
-12x = 3 - 5 simplify
-12x = -2 solve
-x = -2/12
-x = -1/6
(since x is negative, you change the signs on everything...making x positive and the 1/6 positive)

I hope that this helps, I am pretty sure that your teacher did go over this. You were probably in the bathroom or something.

Answer 2

okay first eliminate any addition or subtraction, by performing the opposite operation to both sides. For example in : 9x+2=36, you need tp eliminate the +2 by subtraction 2 from each side of the equation. That leaves you with 9x=34. Now whatever operation is being performed do the opposite. For example divide 34/9 and you get 3.7.

Answer 3

the 1st step is to end the sq.... you're able to try this via taking a million/2 of the 2d term and then subtracting or including from the 0.33 term to end the sq.... subsequently, a million/2 of two is a million and in an attempt to get a million you will desire to subtract 2 yet then upload 2 to maintain each and every thing balanced... x^2 + 2x + 3 - 2 = -2 x^2 + 2x + a million = -2 (x + a million)^2 = -2 And there you pass :D

Glad it's been answered with great explanation. Best of luck.
