Simplify 19/4a to 19a/4

61/28 + a = 19a/4 - 11/7

Multiply both sides by 4

61/7 + 4a = 19a - 44/7

Subtract 4a from both sides

61/7 = 19a - 44/7 - 4a

Simplify 19a - 44/7 - 4a to 15a - 44/7

61/7 = 15a - 44/7

Add 44/7 to both sides

61/7 + 44/7 = 15a

Simplify 61/7 + 44/7 to 15

15 = 15a

Divide both sides by 15

1 = a

Switch sides

<u>a = 1</u>
