4x + 6y = 18 & 4x – 2y = 10

Mathematics
1 answer:
kherson [118]2 years ago
8 0

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25

The simplified form of the given expression is 2015

<h3>Simplifying expressions </h3>

The given expression is (x-2)(x+2)(x²+4)-(x²+3)(x²-3)+2022

The expression can be simplified as shown below

(x-2)(x+2)(x²+4) - (x²+3)(x²-3) + 2022

x(x+2)-2(x+2)(x²+4) - x²(x²-3) +3(x²-3) + 2022

(x²+2x-2x-4)(x²+4) - (x⁴-3x²+3x²-9) + 2022

(x²-4)(x²+4) - (x⁴-9) + 2022

x²(x²+4) -4(x²+4) - (x⁴-9) + 2022

(x⁴+4x²-4x²-16) - (x⁴-9) + 2022

(x⁴-16) - (x⁴-9) + 2022

x⁴ -16 -x⁴ +9 + 2022

x⁴ -x⁴ -16 +9 +2022

= 2015

Hence, the simplified expression is 2015
