The general line formula is

TU + UV = TV Substitute the givens into this line formula

Givens

TU = x + 2

UV = 1

TV = 2x - 3

Solution

TU + UV = TV

x+2+1 = 2x - 3 Combine terms on the left

x + 3 = 2x - 3 Add 3 to both sides

x +3 +3 = 2x-3+3 Combine

x + 6 = 2x Subtract x from both sides.

x-x +6 = 2x-x

6 = x
