How do you solve for R in #T+R=M#?

Answer 1

#" "R=M-T#

Given:#" "color(brown)(T+R=M)#

To solve for R your objective is to have R on its own on one side of the equals sign and everything else on the other side.

To have R on its own wee need to remove the 'T'

What you do to one side of an equation you do the other

Subtract (remove) #color(blue)( T)# from both sides giving

#color(brown)(Tcolor(blue)(-T)+R" "=" "Mcolor(blue)(-T))#

But #T-T=0# giving

#" "0+R=M-T#

#" "R=M-T#

To solve for R in the equation T + R = M, you would subtract T from both sides of the equation to isolate R. Therefore, R = M - T.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
