Answer:

Step-by-step explanation:

to find the inverse, there are two steps

1-interchange x and y

2-solve for y

so y=x+1/x

interchange to get x=y+1/y

and solving for y we multiply both sides by y to get xy=y+1

subtract both sides by y yielding xy-y=1

factor out y to get y(x-1)=1

then divide to get y=1/x-1

2 + 3 × (8 + 53 ÷ 1) Can please include the working to it. Thank you,

luda_lava [24]

Step-by-step explanation:

2 + 3 × (8 + 53 ÷ 1)

we first work out the equation in the brackets

so...

(8 + 53 ÷ 1)

division comes first so we divide 53÷1 which is 1 so the equation looks like this:

(8+53)

we work this out and get

then we work the rest out

2 + 3 × 61

multiplication comes first so...

3×61= 183

and

2+ 183= 185

Therefore 2 + 3 × (8 + 53 ÷ 1)= 185

Hope this helped- have a good day bro cya)
