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
