When solving the following system of equations, which variable would be the easiest to solve for? 2x + y = 9 3x - 2y = 17
2 answers:
Answer:
In my opinion, it would be 'y', since it is already on its own (in the first equation) without any coefficients.
Answer:
x.
Step-by-step explanation:
x because if you multiply the first equation by 2 and add the result to equation 2 , the y's will cancel out.
2x + y = 9 Times 2:-
4x + 2y = 18
3x - 2y = 17 Adding:-
7x = 35
x = 5.
