Solve the following system of equations express your answers as an ordered pair in the format (a,b) with no spaces between the number of symbols 2x+7y=-1 4x-3y=-19
Accepted Solution
A:
Double the first equation: 4x+14y=-2 and subtract the second: 17y=17, so y=1. 2x=-7y-1=-7-1=-8, so x=-8/2=-4. The answer is x=-4 and y=1.
