it starts in high school but is not recommended for 9th graders.
Step-by-step explanation:
Answer:
-1, 6
Step-by-step explanation:
x + y = 5
xy = -6
Take first equation and rewrite it. y = -x + 5
Then substitute the new equation in the second one.
x(-x + 5) = -6
-x^2 + 5x + 6 = 0
Divide by -1
x^2 - 5x - 6
(x + 1)(x - 6) = 0
x = -1, 6
Answer:
At the bottom!
Step-by-step explanation:
Put the two equations into the same standard form:
2x-y=8
-5x+2y=3
Now if you add the two equations up, guess what will happen?
You will "eliminate" the y variable, and only be left with the x variable.
Technically, you will get:
2x-y+2+28-5x+29+2y=8+23
-3x+20y=11
-3x=11
Answer: x = 13/3 or x = 4.33333....
Solution: ⅜x -1 +1 = ⅝ + 1
Simplify: ⅜x = 13/8
Multiply both sides by eight: 8 x ⅜x = 133 x 8 divided by 8
Simplify: 3x = 13
Divide both sides by three: 3x/3 = 13/3
Simplify: x = 13/3
