To solve a problem is to find the answer to the problem. To solve an equation is to find the values of the variable(s).
|2x + 3 = 7||Problem to solve|
|2x = 4||Subtract 3 from both sides|
|x = 2||Divide both sides by 2|
|4x = 2y + 6||Problem to solve.|
|4x - 6 = 2y||Subtract 6 from both sides.|
|2x - 3 = y||Divide both sides by 2.|
