Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11

Answer: A. 673.50
Step-by-step explanation:
Answer:
x>5
Step-by-step explanation:
3x>x^2-10
0>x^2-3x-10
(x-5)(x+2)
x>5 and x>-2
x>5 is the only positive solution
It’swould be the second one
