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.

QUESTION 1:

2x - 3y = 13

5x + 3y = 1

QUESTION 2:

x^2 + y^2 = 5

x - y = 1

THANK YOU!

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.
