You divide each side of the equation by 4 . Then you have
x = 15/4 or 3.75
Yeah AL2006 was right you have to divide 4 on both sides because when a variable is connected to a number like that with no sign between them it is multiplication and the opposite of multiplication is division and 4 divided by 4 cancels out because it is 0. 15 divided by 4 is 3.75.
To solve 4 x = 15 , divide both sides by 4, resulting in x = 4 15 or 3.75 . This isolates the variable and gives you the value for x .
