Fantastic not because you find the solution which was easy and could be find by inspection in a few seconds. Not for that, but is fantastic for the clarity and your will to pass on the info from your mind to others. Excellent, worth of praise.

i need to ask, at the adding part, are you strictly suppose to add? When i subtracted i used the second equation to double check and it was correct but the first was wrong. when i added, i used the first to double check and it was correct but the second was wrong, please help

Hi there nice video you did, Just want to just ask when there are 2 simultaneous equations and they are all postive how come your using - numbers to solve it ? 7:09

So then, when you're adding both equations, the positive 15x (blue) and negative 15x (red) can cancel each other out. That makes it easier to solve for y

Why did you choose to change the 5 to -5? What's the concept?
@hackingmathsOFFICIAL
2 жыл бұрын
6:10 All the coefficients (the numbers in front of the letters) are positive. In this case we are eliminating X, so we need to multiply the first equation by -5 and the second equation by 3. So when we add the equations together we multiply by -5. You could multiply by 5 and subtract the equations but that can cause more confusion.

The method does work. Perhaps you made an addition error as negative numbers can be tricky. What was the question you were trying to solve?

Add 4 to both sides of the equation: 3x - 4 = 5 3x - 4 + 4 = 5 + 4 3x = 9

@Eat_Pi

I'm assuming you understood how he got to: 3x + -4 = 5 Adding a negative number is the same thing as just subtracting so you could simplify it as: 3x - 4 = 5 To solve for X you first want get rid of the -4. So you need to add 4 to both sides of the equation: 3x - 4 = 5 +4 +4 The 4s on the left side cancel out so you're left with: 3x = 9 To solve for x, just divide by 3 on both sides and you get: X=3 Hope that helps! I make videos too so if you ever need more help don't hesitate to ask! ✌️
