Christina weighs 17 pounds more than twice her younger sister sarah's weight when both girls stood on a frieght scale, the reading was 179 pounds how much does christina weigh

Christina weighs 98 pounds.

Step-by-step explanation: The formula to solve this problem is x + 17 + x = 179, where x equals Sarah’s weight.

X + 17 + x = 179

First you need to combine the x values:

2x + 17 = 179

Next, subtract 17 from both sides:

2x = 162

Finally, divide both sides by 2:

X = 81

Sarah’s weight is 81 pounds and Christina weighs 17 pounds more, which is 98 pounds. You can double check your work by adding both of their weights (98 + 81) to make sure that your answer is correct.
