- x/2=10 using the mutiplication principle

Solution

using multiplication principle if we multiply both left hand and right hand side by the same number

the equation remain balanced.

here

-x/2 =10

multiplying both sides by 2

2*(-x/2) =10*2

-x =20

multiplying both sides by -1

(-1)*(-x) =(-1)*(20)

x= - 20
