It is true that 36% of 400 is 144.

36%*400 = 0.36*400 = 144

36%*400 = 0.36*400 = 144

When 5x-8>0, x>8/5, we can get 3x+21>0

|5x-8|=3x+21

5x-8=3x+21

5x-3x=21+8

2x=29

x=29/2.

When 5x-8<0, 0<8/5,and at the same time , 3x+21>0, x>-21/7,x>-7.

it means -7the equation is |5x-8|=8-5x=3x+21

8-21=3x+5x

-13=8x

x=-13/8.

|5x-8|=3x+21

5x-8=3x+21

5x-3x=21+8

2x=29

x=29/2.

When 5x-8<0, 0<8/5,and at the same time , 3x+21>0, x>-21/7,x>-7.

it means -7

8-21=3x+5x

-13=8x

x=-13/8.
