I'm stuck when looking for the ordered pair via the substitution method for the following equations;
1) 8x-8y= -32
2)9x+84 = y
Thanks for the help...
I thought you had to use substitution?
Here are the stages required:
1) Divide my bottom equation by 8
2) Substitute for y, leaving you with a single equation in terms of x
3) Collect like terms
4) Solve for x
5) Resubstitute to solve for y.
Post an attempt if you're still unable to get anywhere.
That is his modus operandi...
