Answer:
x= -24
Step-by-step explanation:
-1/4x-2/3x= -6+28
add -6 to 28 but since 6 is a negative its subtraction
-1/4x-2/3x=22
multiply all by 12
-3x-8x=264
add -3x to -8x
-11x=264
divide both sides by -11
x= -24
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
Ans:8542
The answer is 21x-28 hope it helps
The second image is 3 times the size of the first one so 7 times three gives you 21 =m
