In an expression, you only can add and subtract values that have the same variable. (e.g. $x$ $x$ $+ 8 x$ $+8x$ = $9 x$ $9x$ )

$5 x + 8 + 2 x - 3$ $5x+8+2x-3$

From the expression , we can see that $5 x$ $5x$ & $2 x$ $2x$ have the same variable of $x$ $x$ . Thus, we can add or subtract these 2 values!

$5 x + 8 + 2 x - 3$ $5x+8+2x-3$ = $7 x + 5$ $7x+5$

How do you simplify 5x+8+2x−35x + 8 + 2x -3?
