set the 2 equations equal and solve for x 3x+2 = 1/4x +1

So basically just put the numbers in for x, and whichever equation equals the same for both, is my answer?

I 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.

Try plugging in x = 0.3 again 3(.3) +2 = ? 1/4(.3) +1 = ?

3(.3)+2 = 1.7 1/4(.3)+1 = 0.7

you 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)
