We need to solve for x. Let's try problem b:

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:

Let's isolate x, so subtract 1 from both sides:

Since x can't have a coefficient, divide both sides by 3:


So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:

Let's get our whole numbers on the right side. Add 1 to both sides:

Subtract 4x from the right side on both sides:

Since this is not true, your answer would be:
No solution
Answer:
Card 7
Step-by-step explanation:
2+5+7+8+9 =31
Multiples of 6: 6, 12, 18, 24, 30
31-9=22, No
31-8=23, No
31-5=26, No
31-2=29, No
31-7=24, Yes
The only way to get a multiple of 6 is to subtract card 7, so card 7 is the answer.
