Question 622143
Solve for y in each equation


{{{-x + 3y = 10}}}


{{{3y = x + 10}}}


{{{y = (1/3)x + 10/3}}}


-----------------------------


{{{x + y = 2 }}}


{{{y = -x + 2 }}}


======================================

Then graph each equation


{{{ drawing(500, 500, -10, 10, -10, 10,
 graph( 500, 500, -10, 10, -10, 10,(10+x)/3,-x+2)

)}}}


Notice that the two lines intersect at the point (-1,3)


So the solution is (-1,3) which tells us that x = -1 and y = 3
