Question

Determinați valoarea lui ,,a" din : (324:6+345:5 )×2+1237=43 × a + 1354

Answer 1

(324:6+345:5) x2+1237=43 x a +1354

(54+69) x2 +1237=43 x a +1354

123 x 2+ 1237= 43 x a +1354

246 +1237=43  x a + 1354

1483= 43 x a +1354

43 x a=1483-1354

43 x a=129

a=129:43

a= 3

Answer 2

( 324 : 6 + 345 : 5 ) × 2 + 1 237 = 43 × a + 1 354

( 54 + 69 ) × 2 + 1 237 = 43 × a + 1 354

123 × 2 + 1 237 = 43 × a + 1 354

246 + 1 237 = 43 × a + 1 354

43 × a + 1 354 = 1 483

43 × a = 1 483 - 1 354

43 × a = 129

a = 129 : 43

a = 3
