Let's isolate (1/2)x. To do this, subtract 2 from both sides of the equation, obtaining (1/2)x < -7.
Next, multiply both sides by 2 to eliminate the fraction (1/2):
x < -14

For

the value of

is negative, and for

the value is positive which means between

and

there is an x for which the value of

is equal to 0 and therefore there is a solution.

Answer:
Given the equations:
.....[1]
....[2]
Substitute the value of x in [1] we get;'

Use identity: 

Combine like terms;

Subtract 36 from both sides we get;


By zero product property, we get;
y = 0 and 
Substitute these y values in [2] to get x values;
For y = 0 we have;
x = 2(0) +6 = 0+6 = 6
For x = -4.8
x = 2(-4.8)+6 = -9.6 + 6 = -3.6
Therefore, the solution for the given equations are; (6, 0) and (-3.6, -4.8)
