Work Step by Step

Consider the inequality for the variable x, \[\begin{align} & 4x-2>2\left( x+6 \right) \\ & 4x-2>2x+12 \\ & 4x-2x>12+2 \\ & 2x>14 \end{align}\] It implies that, \[x>7\] The value is x is more than 7. On number line it states that all the numbers which are ahead of 7 moving from left to right are the values which satisfy x Hence, the graph of the simplified form of the inequality on the number line is shown above.
