I need to find the linear system for the equations 4x+3=y and x=y2
Any help at all would be great!
And please show me how you did it if possible, thanks!

4 x  1 y = 3
1 x  1 y = 2
 subtract
3 x  0 y = 1
x = 1/3
then y = 4 (1/3) + 3
y = 4/3 + 9/3
y = 5/3
so (1/3 , 5/3)
check
4(1/3) + 3 = 4/3+9/3 = 5/3 right
1/3 = 5/3  2
1/3 = 5/3 6/3 right
