PLEASE HELP ME I NEED HELP 2x + 6y= 12
X + 3y= 6

In solving the system of equations shown above, Sean showed the following steps:
Step 1: x = 6 – 3y
Step 2: 2(6-3y) + 6y = 12
Step 3: 12 – 6y + 6y = 12
Step 4: 12 = 12
Sean’s work is correct. However, there are no variables in Sean’s final step. What can he state as the solution of the system?

3x + 6y=12

Step-by-step explanation:

For every letter there's a 1 for every letter in that problem so that means x=1 and y=1 and that's how sean got 12

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
