Diego tried to solve the equation 1/3 ( x + 15 ) = 3 what was his mistake 1/3 ( x + 15 ) = 3

1/3x = -12

X = 4

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .
