I've been trying to figure this out but I can't seem to find the correct answer...
DIRECTIONS: Find the points of intersection of the groups of the equations, and check your results analytically.
2x - 3y = 13
5x + 3y = 1
x^2 + y^2 = 5
x - y = 1
queston 1) add the equations to get
7x=14 that gives you x, then put x in either of the equations to solve for y.
question 2) solve for x in the second equation, substitute that into the first equation, solve for y.
