What is the first step in solving: 14 + 2X - 3 = 43? Subtract 14 Simplify, 14 - 3 Add 3 Divide by 2

You must get like terms together. 19 and 91 are like terms 8x is its own like term subtract 19 from both sides and you get 8x = 72 now your like terms are together

subtract 19 from 91. this will give you 8X equals 72. then you divide 72 by 8, and therefore X will equal to 9 Hope this helps, Have a nice day, Tag me on anymore you need help with! :) @casaskaka
