Question 45075: Solve each of the following systems by addition. If a unique solution does not exist, state whether the system is consistent or dependent.
2). x-y = 8
x + y = 2
16). 2x-y=4
2x-y=6
32). 3x + 4y =0
5x - 3y = -29
42). 3x + 3y =1
2x + 4y =2

ALL ARE OF SIMILAR TYPE.PLEASE TRY YOUR SELF BASED ON TWO EXAMPLES WORKED OUT BELOW
Solve each of the following systems by addition. If a unique solution does not exist, state whether the system is consistent or dependent.
2). x-y = 8
x + y = 2
ADDING THE ABOVE EQNS.
2X=8+2=10
X=10/2=5
5+Y=2
Y=2-5=-3
16). 2x-y=4
2x-y=6
SUBTRACTING EQN.II FROM EQN.I
0=4-6=-2...NOT POSSIBLE
HENCE NO SOLUTION
THE 2 EQNS.ARE DEPENDENT AND INCONSISTENT
32). 3x + 4y =0
5x - 3y = -29
42). 3x + 3y =1
2x + 4y =2
