Step-by-step explanation:
X-2y=5 ; 2x-4y=10
• x - 2y = 5 • 2x -4y = 10
 -2y = -x+5 -4y= -2x +10
 y1 = ½x - 5/2 y2 = ½x -5/2
• => y1 = y2
 ½x -5/2 = ½x -5/2
 the systems have no solution

Answer:
x^3-8
Step-by-step explanation:
x^3+2x^2+4x + -2x^2-4x-8
+2x^2 and -2x^2 cancel out
+4x and -4x cancel out
