Step-by-step explanation:
Distributive property can be used for the second image (first image is too blurry, sorry). 2 times 4x is 8x and 2 times -3 is -6. I'm guessing the operation before the 4x is an addition sign, so we have 8x-6+4x. Add the like terms. 8x plus 4x is 12x. Now we have 12x-6. That's the simplest form, unless you evaluate it.
