Question

Using elimination method solve this:

a + 6b = 10
a + 2b= -2

Help please! Struggle with these!

Answer 1

Multiply the 2nd equation by -1 and eliminate the 'a' term to get:
-3b = 12
Now you have the value for b. Next, solve for a by using the value you got for "b"

Answer 2

ok so b= -4

Then, a + 2(-4)= -2

-8= -2

a= 4?

i apologize if I completely messed this up, but I wasn't kidding when i said I struggle with this! meaning math in general!!

Answer 3

just put a= -2-2b in the equation
a+6b=10
(-2-2b)+6b=10
-2-2b+6b=10
-2+4b=10
4b=12
b=12/ 3 and then you can put value of b in equation a=-2-2b to find a ;)

Answer 4

ok so

a= -2-2(4)

a=-2-8

a=10

Answer 5

Correct.
