Question

The elimination process
2a+3b=4
-2a+b=12

Answer 1

plus so 4b=16....then get b and a

Answer 2

so how do you get the b and a

Answer 3

2a + 3b = 4
-2a + b = 12
Just add linearly.
2a + 3b = 4
-2a + b = 12
------------
0 + 4b = 16

4b = 16
b = 4

Then plug 4 in for a.

2a + 3b = 4
2a + 3(4) = 4
Just solve for a now :)

Answer 4

Thank you so very much
