how to solve a one step equation when solving a one-step equation or any type of equation you first want to identify the variable in this case your variable is at you all I want to notice that there are two sides of an equal sign the left side and the right side easiest way to identify this is to draw dotted line over the equal sign to separate the left side from the right side another rule of thumb for solving you is to think of opposites for example the opposite of a plus sign is a negative sign the opposite of a negative is a positive education is division the opposite of division is multiplication in this case we have x + 3 the opposite of + 3 would be -3 now remember what you to one side of an equal sign you must do to the other side of an equal sign drawing an equation bar you then add breakdown X plus nothing will give you an act positive 3 - 3 will give you 0 Carytown your equal sign and 5 - 3 gives you to you then clean it up by getting rid of your zero and stating at eco to this would be your solution to your equation a way to check it would be to plug it back in so here is our check 2 + 3 equals 5 5 does equal 5 therefore you've checked it and it is correct let's try some examples we have x + 5 equal first thing I'm doing is drawing a dotted line through the equal sign separating the left side from the right side we then State x + 5 the opposite of plus size would be -5 even put -5 on both sides of the equal sign giving you x + 0 equal to we then clean it up equal to would be our final moving on to the next problem again drawing a dotted line through the equal sign we read x - 2 equals 3 the opposite of -2 so again whatever we do to one side of an equal sign we must do to the other side we then end up with x + 0 equals 5 cleaning it up we end up with f equals 5 and that would be our solution on the bottom we have three x equals 9 whenever you have a number next to a variable that is considered multiplication the opposite of vacation would be division in this case I mean use a division bar to show the math so I'm going to divide both sides by 3 and again you can draw a dotted line through the middle of your equal sign and then we have three x / 3 which leaves us with f equal 9 / 3 is 3 and that is our final answer looking at the next problem we have x / for the opposite of division is multiplication in this case we want a x whatever is on the bottom or the denominator of the fraction it's the for whatever you do again to one side of an equal sign you must do to the other side of the equal sign in this case your fours will cancel out leaving you with x equals 12th and that would be your final answer this is how you solve one step equations
