-30 = T + 50

Question

 what is the value of T

Answer 1

Isolate T on on side of the equation

 

-30 =T +50

 

Subtract 50 from both sides

 

- 30 -50 = T+50 -50

 

this gives  (-80) =T or  T=(-80)

Answer 2

Given the equation, -30 = T + 50 Use the Subtraction rule of inequality (the same number can be added to both sides of an equation)

-30 - 50 = T + 50 - 50

-80 = T

or

T = -80
