Hey there!

Answer (1)

→ 7x - 2y = 5xy

→ 7x - 2y + -5xy = 5xy + -5xy

→ -5xy + 7x - 2y + 2y = 0 + 2y

→ -5xy + 7 x = 2y

→ x (-5y + 7)/-5y + 7 = 2y/-5y + 7

→ x = 2y/-5y + 7

Answer (2)

→ 8x + 7y = 15xy

→ 8x + 7y + -15xy = 15xy + -15xy

→ -15xy + 8x + 7y = 0

→ -15xy + 8x = -7y

→x (-15y + 8)/-15y + 8 = -7y/-15y + 8

→ x = -7y/-15y + 8

Thanks!
