X=1,y=1
1 )4x+2y=6
2 ) x -y=3
2(x2) ) 2x - 2y=6
Hello!
Begin isolating for x by subtracting 2 from both sides:
Further simplify by multiplying both sides by 3:
Multiply both sides by -1 to cancel out the -x:
Answer:
x = 26 , y = 33
Step-by-step explanation:
3x + 2y = 144 (1)
2x + 5y = 217 (2)
3x + 2y = 144
(divide the equation by 3)
x + (2/3)y = 48
x = 48 - (2/3)y
Plug into (2)
2[48 - (2/3)y] + 5y = 217
96 - (4/3)y + 5y = 217
11y/3 = 217 - 96
11y/3 = 121
y = 121×3/11
y = 33
x = 48 - (2/3)y
x = 48 - (2/3)(33)
x = 48 - 22
x = 26

Answer:
(x^2-2)(x+3)
Step-by-step explanation:
x^3 + 3x^2 - 2x - 6
x^2(x+3)-2(x+3)
(x^2-2)(x+3)
