Solve the system by addition. If solution does not exist, state whether the system is inconsistent or dependent.
2x+3y=1
5x+3y=16


The first step in solving this is to multiply one of the equations so that one of the terms cancels out with the one from the other equation. Since you already have 2 3y's, all you need to do is multiply the equation by -1 so that they cancel out. This gives you these equations:
-2x-3y=-1and
5x%2B3y=16


Since the -3y and the 3y cancel each other out, remove them from the equations:
-2x=-1and
5x=16


When you add the terms, you get:
3x=15


Divide both sides by 3:
x=5


Now, you plug this value into one of the original equations:(I'll use the first)
2%285%29%2B3y=1


Multiply:
10%2B3y=1


Subtract 10 from both sides:
3y=-9


Divide both sides by 3:
y=-3


So, your answer is:
x=5 and y=-3
