Question

[ ( a + 260 : 2 ) × 3 + 4 ] × 5 = 2000

Answer 1

$[(a + 260 \div 2) \times 3 + 4] \times 5 = 2000$

$(a + 130) \times 3 + 4 = 2000 \div 5$

$(a + 130) \times 3 + 4 = 400$

$(a + 130) \times 3 = 400 - 4$

$(a + 130) \times 3 = 396$

$a + 130 = 396 \div 3$

$a + 130 = 132$

$a = 132 - 130$

$a = 2$

Answer 2

[ ( a + 260 : 2 ) × 3 + 4 ] × 5 = 2000

( a + 260 : 2 ) × 3 + 4 = 2000 : 5

( a + 260 : 2 ) × 3 + 4 = 400

( a + 260 : 2 ) × 3 = 400 - 4

( a + 260 : 2 ) × 3 = 396

a + 260 : 2 = 396 : 3

a + 260 : 2 = 132

a + 130 = 132

a = 132 - 130

a = 2
