Answer 1

Answer:

write along with reading my ans... then only u will get ans

Step-by-step explanation:

{ ( y - 5 ) / 7 } - { ( y + 3 ) / 5 } = 2

{ ( y / 7 ) - ( 5 / 7 ) } - { ( y / 5 ) + ( 3 / 5 ) } = 2

y / 7 - 5 / 7 - y / 5 + 3 / 5 = 2 / 1

y / 7 - y / 5 = 2 / 1 + 5 / 7 - 3 / 5

{ 5 × y - 7 × y } / 35 = { 35 × (2) + 5 × (5) - 7 × (3) } / 35

{ 5y - 7y } / 35 = { 70 + 25 - 21 } / 35

{ -2y } / 35 = { 74 } / 35

-2y = 74

y = 74 / -2

y = - 74 / 2

y = - 37
