Answer: y= 7/2 = 3 1/2 = 3.5

Explanation:

2 1/4 +y=5 3/4

Multiply both sides of the equation by 4.

2×4+1+4y=5×4+3

Multiply 2 and 4 to get 8.

8+1+4y=5×4+3

Add 8 and 1 to get 9.

9+4y=5×4+3

Multiply 5 and 4 to get 20.

9+4y=20+3

Add 20 and 3 to get 23.

9+4y=23

Subtract 9 from both sides.

4y=23−9

Subtract 9 from 23 to get 14.

4y=14

Divide both sides by 4.

y= 14/4

Reduce the fraction 14/4 to lowest terms by extracting and canceling out 2.

y= 7/2
