Решите уравнение : 1) 8(x-1,4)=0,56 2) (4,6-x)×19=4,18 3) (51,32+ x)×0,12=72 4) 17,28:(56- x)=36

1. 8 × (x — 1,4) = 0,56 8x — 11,2 = 0,56 8x = 0,56 + 11,2 8x = 11,76 x = [latex] \frac{11,76}{8} [/latex] = 1,47 2. (4,6 — x) × 19 = 4,18 87,4 — 19x = 4,18 —19x = 4,18 — 87,4 —19x = —83,22 x = [latex] \frac{-83,22}{-19} [/latex] = 4,38 3. (51,32 + x) × 0,12 = 72 51,32 + x = [latex] \frac{72}{0,12} [/latex] x + 51,32 = 600 x = 548,68 4. [latex] \frac{17,28}{(56 - x)} [/latex] = 36 17,28 = 36 × (56 — x) [latex] \frac{17,28}{36} [/latex] = 56 — x 56 — x = 0,48 —x = 0,48 — 56 —x = —55,52 x = 55,52
