Answer: The number is 7
Step-by-step explanation:
Let x be the [number]
<u />
<u>Rephrase the expression</u>
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
<u>Calculate</u>
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7
Hope this helps!! :)
