I'm sorry, but I don't understand either of your equations. The first equation has three "equals" signs in it, and the second has two. Each equation should have only one.duffie_stuff said:Solve the following simultaneous equations:
1. 3x - 4y - 7 = y + 10 x = 10 = 4x - 7y
2. 8x + 24 = 15x + 15y = 80 - 10y
Okay, but what are the questions? We still can't understand your "equations".duffie_stuff said:i am using elimination and substitution method to solve both of the questions
Does this mean that your two "equations" are actually two different exercises...? So each "equation" should actually be two separate equations, rather than one "equation" with three "equals" signs...?duffie_stuff said:the answer for Q.1 is (-1, 2) and Q.2 is (12, -4)
And until you tell us what the equations are, we won't know, either.duffie_stuff said:i still do not know how to solve Q.1.
