The standard form is Ax + By = C

1)

2(y) = (1/2x - 10) 2
2y = x - 20
-x + 2y = -20

For #2 does G belong in the equation or is it a mistake, if so let me know so i can answer.

Hope this helps :)

Answer:

x = -3 and y = 0

Step-by-step explanation:

It would be more direct to apply elimination in this problem, rather than substitution:

2x + 6y = -6 ⇒ 2x + 6y = -6 ⇒ 10x = - 30

+ 2(4x - 3y = -12) + 8x - 6y = -24

Now let us solve for x through simply algebra:

10x = -30,

x = -3

Substitute this value of x into the first equation to get the value of y:

2( -3 ) + 6y = -6,

-6 + 6y = -6,

6y = 0,

y = 0
