x=
y=

anonymous · Answer

Solving by substituting means you should substitute some form of the first equation into the 2nd equation...

to get it ready for substitution, you need to rearrange Equation # 1 to solve for the x or the y variable... get it all alone.

So, maybe you would want to solve for y....   x+y = 6   --->>>  y = -x + 6

anonymous · Answer

then take the next step by substituting that expression for "y" in place of the "y" variable in Equation # 2.... then simplify, and solve for x.
