Twice the difference of a number and 4 is equal to three times the sum of the number and 9. Find the number.

Twice the difference of a number and four: 2 (x - 4) three times the sum of the number and 2: 3 (x + 2) 2 (x - 4) = 3 (x + 2) 2x - 8 = 3x + 6-14 = x to confirm2[ (-14) - 4] = 2 (-18) = - 363 [ (-14) + 2] = 3 (-12) = - 36
