Anyone know how you find the range of values of x which satisfy both inequalities simultaneously?*

x^2 - 3x - 4 is greater or equal to 0
and 3x + 1 is greater than 2x + 6*

Find the range of values individually for each inequality.. and then look for their overlap :h:

factorise the top one and then get your values of x.Then rearrange and factorise the bottom one to get your values of x.Then combine values of x that satisfy both ranges.
