To solve the equation "twice the number plus seven is equal to three less than four times the number," we can express it mathematically as ( 2x + 7 = 4x - 3 ). By rearranging the equation, we get ( 7 + 3 = 4x - 2x ), leading to ( 10 = 2x ). Dividing both sides by 2 gives ( x = 5 ). Thus, the number is 5.

100% equals the number. Less than 100% is less than the number. Greater than 100% is greater than the number.
It means that is is less than or equal to that number.
The relational operators are == (equal), != (not equal), < (less than), <= (less than or equal to), > (greater than) and >= (greater than or equal to). All relational operators are boolean, returning true or false depending on the l-value relationship with the r-value, with respect to the operator.

x < /= -4
Please note that <= is meant to be "less than or equal to"... |4x|+3 <= 2 |4x| <= -1 4|x| <= -1 |x| <= -1/4 No solution. No matter what x is, the absolute value signs will produce some positive number on the left side of the equation. And there is no way for a positive number to be less than or equal to -1/4.
