1/3( 5 3/8х+ 1 1/4)=4 пожалуйста помогите! заранее спасибо
1/3 * (5 3/8х + 1 1/4) = 4 5 3/8х + 1 1/4 = 4 : 1/3 5 3/8х + 1 1/4 = 4 * 3 5 3/8х + 1 1/4 = 12 5 3/8х = 12 - 1 1/4 5 3/8х = 11 4/4 - 1 1/4 5 3/8х = 10 3/4 х = 10 3/4 : 5 3/8 х = 43/4 * 8/43 х = 2
1/3*(5 3/8x + 1 1/4) = 4 5 3/8x + 1 1/4 = 4 : 1/3 5 3/8x + 1 1/4 = 12 5 3/8x = 12 - 1 1/4 43/8x = 11 4/4 - 1 1/4 43/8x = 10 3/4 43/8x = 43/4 x = 43/4 : 43/8 x = 43/4 * 8/43 x = 8/4 x = 2
