Question

Solve the simultaneous equations using the elimination method:
4x-3y=5
2x-3y=3
Help PLEASE!

Answer 1

3 appears in both equations. The 3's both have the same sign --> minus.

Use the rule same signs subtract, different signs add.

Subtract top from bottom to get:

2x - 0y = 2
2x = 2
x = 1

Have a nice day. :)

Answer 2

Ops the next one's 2x+3y=3 :\

Answer 3

Ok. Sorry I took this long...

3 still appears in both equations but now they have different signs. The 3 can be eliminated by using the rule: different signs add.

So adding the top and bottom equations we get:
6x + 0 = 8
6x = 8
x = 8/6
x = 4/3

Now to get y we sub x = 4/3 into one of the original equations:

Let's do that with eqn. 2:
2x + 3y = 3
2(4/3) + 3y = 3
8/3 + 3y = 3
--> Multiply everything by 3 to get rid of the fraction:
8 + 9y = 9
9y = 1
y = 1/9

There we go. :)
