1/3( 5 3/8х+ 1 1/4)=4
пожалуйста помогите! заранее спасибо

1/3*(5  3/8x + 1  1/4) = 45  3/8x + 1   1/4 = 4  : 1/35  3/8x + 1   1/4 = 125  3/8x = 12 - 1   1/443/8x = 11  4/4 - 1  1/443/8x = 10  3/443/8x = 43/4x = 43/4 : 43/8x = 43/4 * 8/43x = 8/4x = 2 

1/3 * (5 3/8х + 1 1/4) = 45 3/8х + 1 1/4 = 4 : 1/35 3/8х + 1 1/4 = 4 * 35 3/8х + 1 1/4 = 125 3/8х = 12 - 1 1/45 3/8х = 11 4/4 - 1 1/45 3/8х = 10 3/4х = 10 3/4 : 5 3/8х = 43/4 * 8/43х = 2
