Hey there! I'm happy to help!
We have two values for y in terms of x. We can now create an equation to solve for what x is.
-4x+2=-x-1
We add x to both sides
-3x+2=-1
We subtract 2 from both sides.
-3x=-3
We divide both sides by -3.
x=1
Now, we can plug our x into one of the original equations and then solve for y!
y= -4+2
y=-2
We can also test this with the other.
y= -1-1
y=-2
Therefore, our solution is (1, -2), or x=1 and y=-2.
I hope that this helps!
Answer:
Step-by-step explanation:
x + 6y = 9
-x + 2y = -15
-------------------add
8y = - 6 <=== u see that the x terms cancel each other out
Answer:
the answer is true.. I think
Answer:
y^2 - x^2 = 11
Step-by-step explanation:
y^2 - x^2 = ?
Substitute.
y = 6
x = 5
Becomes:
6^2 - 5^2 = ?
Solve.
6^2 = 6 x 6
6 x 6 = 36
5^2 = 5 x 5
5 x 5 = 25
36 - 25 = 11
