160+3x=195-2x what is the answer

x = 7

Step-by-step explanation:

160+3x=195-2x

Add 2x to each side

160+3x+2x=195-2x+2x

160 +5x = 195

Subtract 160 from each side

160+5x-160 = 195-160

5x = 35

Divide by 5

5x/5 = 35/5

x = 7

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.
