Question

(6-t) + ( 7-T ) - ( 4 - t ) = 0

Answer 1

( 6 - t ) + ( 7 - T ) - ( 4 - t ) = 0

6 - t + 7 - T - 4 + t = 0

6 + 7 - 4 - t - T + t = 0

13 - 4 - T = 0

9 - T = 0

9 - 9 - T = - 9

- T = - 9

- T / - 1 = - 9 / - 1

T = 9

Answer 2

( 6 - T ) + ( 7 - T ) - ( 4 - T ) = 0



6 - T + 7 - T - 4 + T = 0




-T - T + T + 6 + 7 - 4 = 0



T + 9 = 0


T = -9
