Find the sum
Can someone how to find the sum and simpliest form of this equation?(x+4)/5+(2x+1)/5 It is not an equation because there is no = sign. It is a expression. You can simplify it a bit by realising it has a common denominator in both terms. This would be 3x+5 ---- 5

Find the sum of thuis question
Can someone find the sum for this equation please. (X^2)/(X^2-16)=(5X+4)/(X^2-16) I don't think it is finding the sum, but I can simplify the equation. (X^2)/(X^2-16)=(5X+4)/(X^2-16) First, multiply both sides by X^-16. X^2 = 5X+4 Subtract 5X+4 from both sides. X^2-5X-4 = ...
