It would be: 2x+4 = 19
It would be: 2x+4 = 19 and the value of x works out as 7.5
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.
2x + 27
2x + 2 > x + 5
2x+x=3x

twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
3x + (-4) ≥ 2x + 8
To write "twice a number plus six is greater than nine" as an inequality, let the number be represented by the variable ( x ). The expression can be written as ( 2x + 6 > 9 ). This inequality states that when you multiply the number ( x ) by two and then add six, the result is greater than nine.
