Let the unknown number be x:
4x-7 = 13
Moving -7 to the other side of the equation changes it to +7:
4x = 13+7
4x = 20
Divide both sides of the equation by 4 to find the value of x:
x = 5

It equals 28.
The answer is 12. Four times 12 equals 48 (4 × 12 = 48).
4/5 times x = 11
3x - 4 = 8
A negative multiplied by a negative always makes a positive number- so negative four times negative six is simply four times six, which equals twenty-four!
