Помогите решить задачу. Спасибо. Заполните рамочки числами так чтобы получилось верное равенство 1. (x + 5) ⋅ ◻= 3x +15; 2. (9 - y) ⋅ 2 = ◻ - ◻; 3. (◻ + 6) ⋅ 3 = 12x + ◻; 4. (◻ - y) ⋅ 8 = 40 - ◻; 5. (7x + ◻) ⋅ 4 = ◻ + 16; 6. (2x + 11) ⋅ ◻ = 12x + ◻;
1. (x + 5) ⋅ 3= 3x +15; 2. (9 - y) ⋅ 2 = 18-2у; 3. (4 + 6) ⋅ 3 = 12x + 18; 4. (5 - y) ⋅ 8 = 40 - 8у; 5. (7x + 4) ⋅ 4 = 28х + 16; 6. (2x + 11) ⋅ 6 = 12x + 66;
(х+5)*3=3х+15 . (9-у)*2=18-2у . (4х+6)*3=12х+18 . (5_у)*8=40-8у . (7х+4)*4=28х+16 . (2х+11)*6=12х+66
