To simplify, you just condense all of the values with the same variable, based on the signs of those values.
In this example,
6y + 5z + 8y - 3z
is the same as
6y + 8y + 5z - 3z
which can be simplified to
14y + 2z
which is the answer to your question.

Use photomath because it is very helpful bro
. x² + 20 = 12x ⇔ x² - 12x + 20 = 0<span>
D = b </span> ² <span> - 4 a c = 64</span>,
. x₁, ₂ = (- b <span>±</span> √D <span>) / ( 2a)</span> = ( <span>12 ±</span>√<span> 64) / 2</span> = ( <span>12 ± 8) / 2</span><span> ,
. x</span>₁<span> </span><span> = 10 , x </span> ₂ = 2
