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.
