Two step equations are like 8x+5=29. You could write a problem like Cara wants to rent a bike, it cost $5 and $8 per hour. How many hours did she go biking? Subtractst 5 from each side. 8x=24 Divide by 3. X=3 She biked 3 hours

A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3 4

dimaraw [331]

Given :

A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3/4 pounds the first month and 11 5/8 pounds the second month.

To Find :

How much weight must be lost the third month for the goal to be achieved.

Solution :

Let, weight lose in third month is x.

So, 8 3/4 + 11 5/8 + x = 26

$\dfrac{32+3}{4}+\dfrac{88+5}{8}+x=26\\\\x = 26 - ( \dfrac{35}{4}+\dfrac{93}{8})\\\\x=5.625\ pounds$

Therefore, weight lose in third month is 5.625 pounds.

Hence, this is the required solution.
