How many solutions does this system have?
Leokris [45]

Answer:

The correct option is d.

Step-by-step explanation:

The given equations are

x-2y=2                 .... (1)

y=-2x+5               .... (2)

In equation 2, multiply both sides by 2.

2y=-4x+10               .... (3)

Now add equation (1) and (3).

x-2y+2y=2+(-4x+10)

x=2-4x+10

x+4x=12

5x=12

Divide both sides by 5.

x=\frac{12}{5}=2.4

Put this value in equation (2).

y=-2(2.4)+5

y=-4.8+5

y=0.2

Therefore the solution of the system of equation is (2.4,0.2) and the system has only one solution. Option d is correct.
