x + 14.5 = 156.5
x + 14.5 = 156.5
x – 14.5 = 156.5
x – 14.5 = 156.5
7x + 14.5 = 156.5
7 x + 14.5 = 156.5
7x – 14.5 = 156.5
x - 14.5 = 156.5
The equation that can be used to find how much Ernesto weighed before is:
x + 14.5 = 156.5
To find out how much Ernesto weighed before, we can use the given information that he lost 14.5 pounds in 7 months and now weighs 156.5 pounds.
Let's assign a variable to represent Ernesto's previous weight before losing 14.5 pounds. Let's call it "x".
Since Ernesto lost 14.5 pounds, we can subtract that amount from his current weight of 156.5 pounds. So the equation becomes:
x - 14.5 = 156.5
Therefore, the equation that can be used to find how much Ernesto weighed before is:
x - 14.5 = 156.5
