Use one equation to isolate either x or y.
4x = 11 + 2y
x = 11/4 + 1/2y
Substitute that value for x in the second equation and solve for y. Put that value back in the first equation to solve for x. Check by putting both values into the second equation.
Subtract y from x.
I hope this helps. Thanks for asking.
Use the solution of the system below to find x-y:
4x-2y=11
3x-4y=-6
a 11.3
b 0.1
c -0.1
d -11.3
please explin how to do this.
Thanks!!!
