y is increased by 6.
let x be the number, then: (x + 1) × 2 + 5 = x + 1 → 2x + 2 + 5 = x + 1 → 2x + 7 = x + 1 → 2x - x = 1 - 7 → x = -6 The number is -6. Checking: -6 +1 = -5; 5 × 2 = -10; -10 + 5 = -5 which is the same as -6 + 1 = -5.
Add 8 to x. If x is 5 then 14. If x is 6 14 etc
Let x equal the unknown number(3*x)+6 = -243x = -30x = -10
OMG more easy... (Without equations) percent increase = [amount * (1 + x%)] x% = x/100; 6% its (6/100) = .06 200000*1.06 = 212,000

It could be either 4/x + 6 or 4/(n + 6).

1/2 x + 6 = 11 1/2 x + 6 - 6 = 11 - 6 1/2 x = 5 2*(1/2 x) = 5*2 x = 10 1/2 of 10 is 5, 5 plus 6 is 11 QED
The number is 9. 9 x 6 = 54 - 9 = 45.
