Answer 1

Răspuns

a = 25 275

Explicație pas cu pas:

(a x 8 + 450 x 250) : 3 147 + [83 x 6 x 8 - (20 000 - 16 216)] = 300

(a x 8 + 450 x 250) : 3 147 + (83 x 6 x 8 - 3784) = 300

(a x 8 + 450 x 250) : 3 147 + (3984 - 3784) = 300

(a x 8 + 450 x 250) : 3 147 + 200 = 300

(a x 8 + 450 x 250) : 3 147 = 300 - 200

(a x 8 + 450 x 250) : 3 147 = 100

a x 8 + 450 x 250 = 100 x 3 147

a x 8 = 100 x 3 147 - 450 x 250

a x 8 = 314 700 - 112 500

a x 8 = 202 200

a = 202 200 : 8

a = 25 275

Answer 2

(ax8+450x250):3147+[83x6x8-(20 000- 16 216)] = 300

(ax8+112 500):3147 + (3984 - 3784) = 300

(ax8+112 500):3147 + 200 = 300

(ax8+112 500):3147 = 300-200

(ax8+112 500):3147 = 100

ax8+112 500 = 100x3147

ax8+112 500 = 314 700

ax8 = 314 700 - 112 500

ax8 = 202 200

a = 202 200:8

a = 25 275
