If x = 3 and y = 4 then the answer is 2
0
x + 2y = 83x - y = 3Need to rearrange first for easier calculation (get y and x on different sides) so...x + 2y = 8 is the same as 2y = 8 - x is the same as y = 4 - 0.5x3x - y = 3 is the same as y = 3x - 3Lines intersect when the functions equal each othery=y4 - 0.5x = 3x - 37 - 0.5x = 3x7 = 3.5x2 = xput x value into either equation to find y valuey = 3(2) - 3y = 3Lines intersect at point (2,3)
