Answer:

w+2,312=2,490

w= 178 pounds

Step-by-step explanation:

Let

W—-^ the amount of weight Bernard lost in pounds

We know that

The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week

So…

The linear equation that represents this situation is

w=2,312=2,490

solve for w

Subtract 2,490 - 2,312 = 178lbs
