Question

solve the equatoon 2x + 8 = 0 and represent the number line snd cartesian plane

Answer 1

Step-by-step explanation:

The equation 2x + 8 = 0;

By solving this equation by variable separation method:

-

we get ,

2x = -8;

x = -8/2;

x = -4;

This coordinate is exist on the negative x axis it means the line is parallel to y axis and passing through the x axis.

There is only one solution is exist for this equation.

Answer 2

Answer:4

Step-by-step explanation:

2x+8=0

2x=0+8

2x=8

X=8/2

X=4
