The second answer which is b the answer is 10 all you do is combine like terms then plug it in and do the next step ill reply when i get the second one
So if an equation was f(x)=x+4
you would automatically change f(x) into y
so it would y-y=x(x-x)
so you plug in the x and 4 which is the first y and x
y-4=x(x-x)
you switch the numbers around
so your final answer would be x-4
1x1x1=1
2x3x4=6x4=24
1/24
please mark me brainliest I'm trying to level up
