Drag the system of equation to the point that represents the solution to the system.

solving of the system equation:  2x-y=-13 ⇒(1)   and    y=x+9 ⇒(2)

by substituting from (2) at (1)

2x-(x+9)=-13

2x-x-9=-13

x=-4 ⇒ substituting at (2)  ∴  y = -4+9 = 5

The point that represents the solution to the system = (-4,5)

solving of the system equation: 3x+2y=10  ⇒(1)  and  6x-y=10  ⇒(2)

by multiplying equation (2) ⇒    12x-2y=20 ⇒(3)

adding (1) and (3)

                           15 x = 30 ⇒   x=2

from equation (2)  6x-y =10  ⇒⇒⇒ y = 6x-10 =12-10=2

The point that represents the solution to the system = (2,2)

solving of the system equation: 4x-3y=5  ⇒(1)  and  3x+2y=-9  ⇒(2)

solve for x, y

we find   x=-1  and y=-3

The point that represents the solution to the system = (-1,-3)

solving of the system equation:  x+y=7 ⇒(1)   and    x-y=-1 ⇒(2)

adding (1) and (2)

                          2x=6  ⇒⇒⇒ x = 3

substitute at (1)

                        y =7-x=7-3=4

The point that represents the solution to the system = (3,4)

solving of the system equation: y=3x-7  ⇒(1)  and  y=2x-5  ⇒(2)

equating (1) and (2)

solve for x and y

we find  x=2  ⇒⇒⇒ y = -1

The point that represents the solution to the system = (2,-1)

The system equation : y = 6    and  x =-5

The point that represents the solution to the system = (-5,6)

The attached figure represent a conclusion for the answer

Step-by-step explanation:

because it is

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
