well, it's quite simple, now you have 39+2x=55, now you need to substract 39 on both sides

39-2=37

39-55=-16

Answer 59

no, you got it wrong, you can't calculate a number with an x with a number without x

Answer 60

oh sorry

Answer 61

you substract 39 on both sides : 39-39+2x=55-39

Answer 62

39-39=0 39-55=-16

no, 55-39, not 39-55

16

and then divide both side by two so you dont have 2x anymore but just x left

so divid 55by 2 then 39 by 2

no, 16 by two

16/2=8 and 2/16=0.125

Answer 73

right

Answer 74

the answer is 8

Answer 75

Solve.

8 – 3x – x = 12

Combine the two "x" terms: Solve.

8 – 4x = 12

Subtract 8 from both sides: Solve.

8 – 4x = 12
-8 -8
--------------
-4x = 4

Divide both sides by -4.

What is x?
