3x+4y>44

A linear inequality.
3x + 4y > 44
4y> -3x + 44
y> -3/4x + 11
Draw the "equals" part. In other words, draw the line y = -3/4x + 11. Your answer is the "greater" part above the line you just drew.

Is that the whole problem? Are you supposed to graph it? You can't solve for the variables when there are 2 in the one equation.
You can rewrite it in slope form of a line to graph:
y > (-3/4)x + 11
On a graph, you would make a point at 11 on the y-axis (0,11) and the slope is down 3, over 4 to the right, so your second point would be at (4,8). And since it's an inequality, you would have to shade the side of the line on the right. Also, since it is y > (less than but NOT equal to), the line needs to be dotted.
I hope that makes sense. Good luck!

x = 12
y = 2
(3 x 12) + (4 x 2)= 44
36 + 8 = 44

an inequality...
just kidding...Do you need it graphed (It's a line.) or what? Solving it is not an option without more info or trial & error since you have 2 variables.
quatt's math looks correct, but it was solved with trial & error...one other note to his answer is that the = should be changed back to an inequality...in this case it would be anytime x & y are greater than the solution he gave you.
Matt & Bongernet did a good job in explaining how to graph it.
