"Solve Simultaneously."
"2x+3y=8
3x+2y=7"
"5x-4y=27
4x-5y=18"
I know I have to add/subtract somewhere...But not sure where...
Can someone help me, please?
-We are gonna get the value of x from first equation
-We will put that in second equation
-This gives an wequation in y
-Get value of y
-And thus the value of x
1st one:
2x+3y = 8
2x = 8 - 3y
Hence
Put the value of x as in 1
Hence
Hence
Thus
And
2nd One ;
Put the value of x from 1 here
Hence
Thus
