What is the solution to the system of equations 2x-5y=-5 and x+2y=11?
1 answer:
Let's eliminate x in the system <span> 2x-5y=-5 x+2y=11 To do this, mult. the 2nd eqn by -2: </span> 2x-5y=-5 -x-4y=-22 --------------- -9y= -27. This yields y = 3. Now subst. 3 for y in either of the original equations to determine x. Write your answer as an ordered pair: ( ? , 3).
