Question

solve the equation 2x+8=0 and represent the solution on (i) the number line . (ii)the cartesian plane​

Answer 1

Answer:

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

2x+8=0

2x=0-8

2x=-8

X=-4
