Solve 9x - 3 = 4x + 17
The objective of the question is to find an answer to x = ?, where ? is a number.
Start by 'moving' all the x's to one side of the equals sign and all the numbers to the other. This can be done by adding / subtracting the values from both sides.
9x - 3 - 4x = 4x + 17 - 4x goes to 9x - 4x - 3 = 17
9x - 4x - 3 + 3 = 17 + 3 goes to 9x - 4x = 17 + 3
Boths sides of the equation are then to be simplified
5x = 20
Divide both sides by the coefficient of x (the number before the x) which is 5 in this case
5x / 5 = 20 / 5
x = 4
