Please help algebraic proofs
if anyone can do 4 and 5 that would be awesome

4. given 16x - 10 = 4x+ 2
prove: x = 1

5 given x/5 + 3 =2x-24
prove x=15

u will get 10 points!!

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
