Question 766081: 4x+3y=1
x=1-y
Answer by mananth(16946)   (Show Source):
You can put this solution on YOUR website! 4 x + 3 y = 1 .............1
Total value
1 x + 1 y = 1 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by -3
4 x 3 y = 1
-3 x -3 y = -3
Add the two equations
1 x = -2
/ 1
x = -2
plug value of x in (1)
4 x + 3 y = 1
-8 + 3 y = 1
3 y = 1 + 8
3 y = 9
y = 3
x= -2
y= 3
