With that information we can conclude that she spent $70 which $44 of it was spent in a table. with that information we can create thr equation 2x + 44 = 70 where x is the price of 1 chair Now that we created our equation we just need to isolate it by subtracting 44 from both sides of the equation: 2x + 44 - 44 = 70 - 44 2x = 26 Now we can divide both sides by 2 and find how much each chair (x) costs 2/2x = 26/2 x = 13 So each chair costs $13 I hope you understood my brief explanation
