Answer

x:(-6, -1)

Work Step by Step

Our two inequalities are: 3x<4x+6 2x+1<15 For the first equation lets solve for x. 3x<4x+6 (Subtract both sides by 3x) 0-6 For the second equation, lets solve the second equation for x as well. We will do this by subtracting 1 and dividing by 2 to both sides of the equation. We get: x<1 Now the only values of x that are in common with both inequalities are values between -6 and -1 (non inclusive). So we can write our solution as x:(-6, -1)
