Answer:
2x - 4 = 16
Step-by-step explanation:
'the difference' shows that its subtraction so u have to put a - in the equation
'double' means 2 and since you dont know the value of 'a number' you replace it with a variable like x. combine them and you get 2x
so far it should look like 2x -
4 is equal to 4 so just put a 4 in front of the subtraction sign
it'll look like 2x - 4 now
'is 16' basically means is equal to 16 so now ur equation should look like:
2x - 4 = 16
if you wanted to solve that u could add 4 to both sides then divide both sides by 2 and get x = 10
Answer:
x = 10
Step-by-step explanation:
2x - 4 = 16
2x = 20
x = 10
Hope that helps!
