Question

1800 x { [ 1926 : 6 + 218 - ( 800 - 873 : 3 ) ] : [ 10 000 - 5 x 1 000 - ( 8 x a + 1342 ) ] } = 5400
a = ?
Help me fast.

Answer 1

1800 X {[321 + 218 -(800 - 291)]} :[10000- 5000 - (8 X a + 1342)]} = 5400

1800 X (539 - 509) : [5000 - (8 X a + 1342)] = 5400

1800 x 30 : [( 5000 - (8 x a + 1342)] = 5400

30 : [( 5000- (8 x a + 1342)] = 5400 : 1800

30 : [(5000- (8 x a +1342)] =3

5000 - (8 x a + 1342) = 10

8 x a + 1342 =4990

8 x a = 3648

a = 456.
