Answer:
x=2, y=2
Step-by-step explanation:
3x + y = 8
2x + 4y = 12
Multiply the first equation by -4
-12x -4y = -32
Then add to the second equation
-12x -4y = -32
2x + 4y = 12
------------------------
-10x + 0y = -20
-10x = -20
Divide by -10
-10x/-10 = -20/-10
x =2
Now find y
3x+y = 8
3(2)+y = 8
6+y = 8
y = 8-6
y =2

Solving:

Delete the first parentheses by the distributive property, with the distributive property, we multiply the '3' first, then resolve it and the second parentheses eliminate by changing the sign:

<span>Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.

Answer:
I am not too sure but i think 6+5=11
Step-by-step explanation:
where 6 comes first then 11 comes second and that equals 11
The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.
But it becomes a lot less steep. The original line only had to go <em>4 inches</em>
to the right in order to rise 1 foot. The new line has to go <em>3-feet</em> to the right
in order to rise 1 foot.
