Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100

I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)
1) distribute 2 to each term within the parentheses
2) combining like terms ( which means subtract a 6-2)
3) subtract 4 from both sides of the equation
4) divide both sides of the equation by 4
Final answer should be ( x = 1/4 )
3x + 9 = 2x + 12
-2x -2x
1x +9 = 12
-9 -9
x = 3
