The tens are double the ones: c= 2d
the thousands are double the tens:
a = 2c = 4d
the sum of the digits is 19:: a+b+c+ d = 19
Substitute for a and c to get:
4d + b + 2d + d = 19
b + 7d = 19
d=2;b=5;0=4;a=8

Answer:
x = -12
Step-by-step explanation:
2(x+1)-3x=14 (expand parenthesis i.e PEDMAS rule)
2x + 2 - 3x = 14 (bring all x terms to one side and numbers to the other; subtract 2 from both sides)
2x - 3x = 14 - 2 (evaluate each side)
-x = 12 (multiply both sides by -1)
x = -12
