Ok so at first this problem may seem confusing but no worries. MATH is like that so our first step is to combine like terms which are the variables in the equation . So we have 2x+3-x+5 so like I said combine like terms is the first step so 2x and 1x are like terms because they have the variable x involved so when we subtract we get a result of 1x now wr have to add the constants which afr the numbers without variables which would equal the final form 1x+8 your answer is d
