Question 144150: How can you solve the systems of euations using elimination with the equations: 3x-5y=11 and 4x+3y=5
It's for my Algebra Final Examination, so I need help fast!
One way is to eliminate one of the variables. Multiply the 1st eqn by 4 and the 2nd by 3, giving:
12x-20y=44 and
12x+ 9y=15. then, subtract eqn 2 from eqn 1, giving
0x -29y=29, or 29y = -29.
So y = -1. Sub -1 in for y in eqn. 1 or 2, giving 3x -5(-1) = 11, or 3x + 5=11.
Then 3x = 6, x=2.
