Question

How do I find the systems of these and graph them?

3x + 6y - 12 = 0
x + 2y = 8

Answer 1

these are two straight lines
plot values of x say -4 to 4 and their y values
where they intersect gives you the coordivates of the solution of the system

Answer 2

Can you go by steps?

Answer 3

3x + 6y - 12 = 0
x + 2y = 8

Solve both equations for y:

\[y = \frac{12-3x}{6}\]\[y = \frac{8-x}2 \]

Set y = y and solve for x:
\[\frac{12-3x}{6} = \frac{8-x}{2}\]

\[2(12-3x) = 6(8-x)\]

\[24 - 6x = 48 - 6x\]

No Solution

Answer 4

do u want to solve them firsr ?
