Answer:

RT = 86

Step-by-step explanation:

23x - 6 = 2(15x - 17)

23x - 6 = 30x - 34

23x - 30x = - 34 + 6

-7x = -28 |÷(-7)

x = 4

RT = 23x - 6 = 23 × 4 - 6 = 92 - 6 = 86

12 = 3x   [from subtracted 1 from both sides]
x = 4      [from dividing 3 from both sides]

therefore your answer would be  x = 4
