Answer:

$10x^{2}-34$

Step-by-step explanation:

Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).

$2((3x^{2}+x^{2}-5)+(x^{2}-12))$

Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.

$2(5x^{2}-17)$

Now we can distribute the 2 by multiplying each value in the parentheses by 2.

$10x^{2}-34$
