<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1

Step-by-step explanation:
Answer:
8(X^2+1)
Step-by-step explanation:
(X²+3)²-(X²-1)
(X²+3)(X²+3)-(X²-1)(X²-1)
X⁴+3X²+3X²+9-(X⁴-X²-X²+1)
X⁴+6X²+9-(X⁴-2X²+1)
X⁴+6X²+9-X⁴+2X²-1
8X²+8
If you factor 4x²-12x, you can divide 4x from each term.
4x² ÷ 4x = x
-12x ÷ 4x = -3
Therefore, the other term becomes (x-3) because 4x(x-3) = 4x²-12x
