Question

use the method of elimination to solve the system of linear equations a+8b=10
a+4b=2

Answer 1

a+8b-a-4b=10-2, then 4b=8 so b=2, a+8=2 then a =-6

Answer 2

wut?!

Answer 3

make both equal to zero
a+8b-10=0.....(1)
a+4b-2=0....(2)

subtract (1) (2)
4b-8=0
4b=8
b=2

sub. in original equation (1)
a+8b=10
a+8(2)=10
a=-16+10
a=-6
