How do you solve the simultaneous equations # 4x - 2y = 6 # and #3x + y = 17#?
You can isolate one of the variables in one of your equations and plug it into the second. X equals 4.
Isolate one of the variables in one of the equations. Here, it's easier to isolate the y of the second equation.
Now, you can plug in what you got for y into the FIRST equation.
Develop your answer and move similar terms to each side.
Solve for x.
y = 5, while x = 5
Then rearrange B to get it in terms of y, since it already has y on it's own.
Thus gives us B:
Then substitute this value of y into equation A:
thus we get
if we rearrange this, we get
If we put this into the rearrange form of B: we get
