Answer:
x = 5
y = 4
Step-by-step explanation:
just substitute the value of one variable into the other
-x +y = -1
or y = -1 +x <-------- (i just added x to the right side)
now u know what y is equal to, just substitute that value into the first equation
2x - (-1+x) = 6 <-------- instead of y, i put the value of y from the 2 equation
NOW SOLVE FOR X!
2x +1 -x = 6
x + 1 = 6
x = 5
now solve for y since you have the value of x
y = -1 + x
or y = -1 + 5
y = 4
<span>n² + 2n – 24=0
</span><span>n² + 6n-4n – 24=0
</span><span>n(n + 6) – 4(n+6)=0
(n+6)(n-4)=0
Hence,
n=4
or
n=-6</span>
