Simplify the expression:<br><br> 5x + 8 – 13y – 4x – 18 + 16y

aleksandrvk [35]

$\text{Hey there!}$

$\text{Simply the equation: 5x + 8 - 13y - 4x - 18 + 16y}$

$\text{First you have to combine the \bf{like-terms}}$

$\text{5x-4x = 1x}$

$\text{-13y + 16y = 3y}$

$\text{8 + (-18) = -10}$

$\boxed{\boxed{\bf{Answer: 1x + 3y - 10}}}\checkmark$
