Answer:
Three more than twice a number is equal to four less than the number. Find the number.
Let the number be x.
- Three more than twice a number = 2x + 3
- Four less than the number = x - 4
Equation :
2x + 3 = x - 4
Solve the equation :
2x + 3 = x - 4
2x - x = - 4 - 3
x = - 7
So, the number is - 7.
