Anyone knows this ans? I will mark them BRAINLIEST... The one who ans first and gives complete ans...thanks for helping!

a) r = 5

b) t = 5/3

c) a = 1

d) x = 0

How to solve an eqution:

Equation solving is So easy you just need to follow the instructions.

i) First arrange the no. in one side and variable in one side.

ii) The sign will change if we change the no. or variable between equal =. Like + change into - and × change into ÷ .

iii) Use the BODMAS and just go ahead.

Solution:

Just Click on _______

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.
