Three less than 30 is 27. To find this, you simply subtract 3 from 30, which results in 27.
When you subtract one square number from another and the result is 27, you can express this as ( a^2 - b^2 = 27 ), where ( a ) and ( b ) are integers. This can be factored into ( (a - b)(a + b) = 27 ). The pairs of factors of 27 are (1, 27), (3, 9), and their negative counterparts. Solving these pairs will yield possible values for ( a ) and ( b ).
6x+3=27 6x=24 (subtract 3 from each side) x=4 (divide both sides by 6)

To work out the answer to 3 plus 3 x 3 - 3 plus 3, you add 3 and 3 together which is 9, multiply 9 by 3 which is 27, subtract 3 which is 24 and add 3 to get the answer which is 27.

-27 You subtract powers of 2 everytime... 1,2,4,8,16
Well, honey, if you want to subtract your way to 27, you could start at 54 and subtract 27. Or you could go wild and subtract 0 from 27, but that's just too easy for someone like you. Just remember, the answer is always right under your nose, darling.

3x + 6 = 27.Subtract 6 from both sides: 3x = 27 - 6 = 21.Divide both sides by 3: x = 21/3 = 7.x = 7
Subtract 1.
