2x squared +1 - 7x squared +3
Answer:
x =
Step-by-step explanation:
2x – 4 – (x + 2) = 6x is the given equation
Now simplifying both sides, we get
2x - 4 - x - 2 = 6x
taking like terms on each side of the equality, we get
2x - x - 6x = 4 + 2
or, -5x = 6
or x =
hence, the value of x =
Answer:
8
Step-by-step explanation:
16 divided by 8 equals 2 then 24 divided by 8 equals 3 Answer: 8
-4x + 7y = 9 ⇒ -4x + 7y = 9 ⇒ 8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ <u>-35x - 14y = 154</u>
<u>43x</u> = <u>-172</u>
43 43
x = -4
-4x + 7y = 9
-4(-4) + 7y = 9
16 + 7y = 9
<u>- 16 - 16</u>
<u>7y</u> = <u>-7</u>
7 7
y = -1
(x, y) = (-4, -1)
Answer:
(-6,-4)
Step-by-step explanation:
So there actually is really easy way to solve this problem(that many people will never teach you for some weird reason).
Find difference between two points first in x and y direction.
X difference = (-3 - (-8)) = 5
Y difference = (-1 - (-6)) = 5
Multiply 2/5 to each difference
X difference 5 * 2/5 = 2
y difference 5* 2/5 = 2
just add the two number to First point(point A)
-8 + 2 = -6
-6 + 2 = -4
(-6,-4)
