Answer:

Step-by-step explanation:

let the number be x then twice the number is 2x, hence

42 + 2x = 164 ( subtract 42 from both sides of the equation )

2x = 122 ( divide both sides by 2 )

x = 61

Hence the number is 61

How do I solve this??

pshichka [43]

Well, first you should make both sides of the equation to the power of 2.
So, you'll have 7X = 1225, and then X is 175 :)

Have a wonderful day!
