Question

Can anyone help me with one problem?

Answer 1

(I also only need to solve using one method and I know it would be elimination or substution)

Answer 2

Substitution is the best for the last one

Answer 3

Elimination for the first two

Answer 4

I finished the first 2 I'm just confused with the last

Answer 5

In the third one, you already have y as the subject.

Answer 6

You just substitute
\[\frac{ 1 }{ 2 }x-6\] for every "y" you see in the second equation.

Answer 7

\[2x+6(\frac{1}{2}x -6)=19\]

Answer 8

Okay

Answer 9

Do you know how to work it out from there?

Answer 10

Yeah I believe so, thank you

Answer 11

No worries.

Answer 12

So wait, is this correct then

Answer 13

2x + 6 [ (1/2)x - 6 ] = 19
2x + 3x - 36 = 19
5x = 55
x = 11

y = 11/2 - 6
y = -1/2

x = 11 , y = -1/2

Answer 14

reminds me I should make a tutorial on solving linear equations in openstudy :)

Answer 15

Correct @veganbee Awesome work.
