Best ResponseYou've already chosen the best response.0set the 2 equations equal and solve for x 3x+2 = 1/4x +1

Best ResponseYou've already chosen the best response.1So basically just put the numbers in for x, and whichever equation equals the same for both, is my answer?

Best ResponseYou've already chosen the best response.1I tried plugging in all the numbers for x and none of them equal the same.. or am I doing the wrong thing for this problem? I don't get it.

Best ResponseYou've already chosen the best response.0Try plugging in x = 0.3 again 3(.3) +2 = ? 1/4(.3) +1 = ?

Best ResponseYou've already chosen the best response.1you must solve it graphically so you only need to find the point of intersection between the two lines y = 3x + 2 & y = 1/4 x + 1 from the graph then the solution is (0.3, 1.1)
