Answer:
x=7
Step-by-step explanation:
since it is the same side length,
3x+6 = 10x-43
3x-10x = -43-6
-7x = -49
x=-49/-7=7

Answer:
Step-by-step explanation:
x-y=7
-3x+9y=-39
Divide the second equation by 3
-x +3y = -13
Add this to the first equation
x-y=7
-x +3y = -13
----------------------
0x +2y = -6
Divide by 2
2y/2 = -6/2
y = -3
Now find x
x-y = 7
x -(-3) = 7
x+3 = 7
Subtract 3 from each side
x = 4
(4,-3)
Or by substitution
x-y=7
solve for x
x = 7+y
-3x+9y=-39
Substitute y+7 in for x
-3(7+y) +9y = -39
Distribute
-21 -3y +9y = -39
Combine like terms
-21 +6y = -39
Add 21 to each side
6y = -18
Answer:
I believe the slope would be -2
Step-by-step explanation:
The line goes <u>down 2</u> boxes and <u>over 1</u> box before it intersects with another point. Knowing slope = 
, we know that slope = 
which is equal to -2.
