Solve for m:
5m - (-8) = (-4) + 2m

Solve for x:
3x + 8 < 2x - 15

5m - (-8) = (-4) + 2m=  m=−4 solvi

3x + 8 < 2x - 15= x<−23

Step-by-step explanation: 5m - (-8) = (-4) + 2m=  m=−4

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    5*m-(-8)-((-4)+2*m)=0

Pull out like factors :

  3m + 12  =   3 • (m + 4)

Solve  :    m+4 = 0  

Subtract  4  from both sides of the equation :  

                     m = -4

3x + 8 < 2x - 15

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                    3*x+8-(2*x-15)<0

Subtract  23  from both sides

           x < -23

x < -23
