Best ResponseYou've already chosen the best response.1You have to isolate the variable

Best ResponseYou've already chosen the best response.1i.e. 5x  4 = 21 (i made this up) So we need to leave x alone

Best ResponseYou've already chosen the best response.1To do this, we need to cancel out everything on one side and move it to the other side to find the value of x

Best ResponseYou've already chosen the best response.15x  4 = 21 Let's get rid of 4 first. The opposite of 4 is +4 so we must add 4 on both sides of the equation. 5x  4 + 4 = 21 + 4 5x = 25

Best ResponseYou've already chosen the best response.0So for example If i had 113f+8=r how would i approach the problem.

Best ResponseYou've already chosen the best response.1Now we cancel out the 5 The opposite of multiplying 5 is DIVIDING it. 5x/5 = 25/5 x = 5

Best ResponseYou've already chosen the best response.1Ok well that one is three steps actually

Best ResponseYou've already chosen the best response.1First look at 11 and 8. These are like terms so just combine them. 11 + 8 = 19

Best ResponseYou've already chosen the best response.1Now we have 19  3f = 4

Best ResponseYou've already chosen the best response.1WE get rid of anything without a variable first, so what is the opposite of adding 19?

Best ResponseYou've already chosen the best response.1I say adding because even tho it is at the beginning of the equation, it is positive.

Best ResponseYou've already chosen the best response.0How would i solve for x thought?i believe it is subtracting 19 from 3 right?

♪Chibiterasu

Best ResponseYou've already chosen the best response.1We can't do that because 3 is attached to a variable. you cant to 19  3f because we dont know what f is. if 19 had the same variable we could i.e. 8f  3f = 5f but we cant, so we need to bring 19 to the other side of the equation

Best ResponseYou've already chosen the best response.1WE have to cancel it out. So the *opposite* of +19 is what?

♪Chibiterasu

Best ResponseYou've already chosen the best response.1Yep. So we subtract 19 on BOTH sides of the equation. We do it on both sides to make it equal. 19  19  3f = 4  19 what do we have now after subtracting?

Best ResponseYou've already chosen the best response.0Add our left over variables.

Best ResponseYou've already chosen the best response.1What do we get when subtracting 19 on both sides?

♪Chibiterasu

Best ResponseYou've already chosen the best response.1Noooo we have: 3f = 15 19  19 just cancels out and we had to subtract 4  19

♪Chibiterasu

Best ResponseYou've already chosen the best response.1WE make 3 negative because that was the sign that was in front of it

♪Chibiterasu

Best ResponseYou've already chosen the best response.1Now what do you think we do to remove 3 from the f?

♪Chibiterasu

Best ResponseYou've already chosen the best response.1Yes, but 4  19 can just be simplified to 15 3 * f = 15

Best ResponseYou've already chosen the best response.0I get it now thanks!!!

Best ResponseYou've already chosen the best response.1Yeah, just remember to divide 3 on both sides to cancel out and isolate x.
