let numerator be x and denominator be y
x = y-3...eqn 1
{(x +7)/ (y+5) } - x/y = 1/2... eqn 2
expandin eqn 2...
2y(x+7) - 2x(y+5) = y(y+5)
=》 2xy + 14y - 2xy -10x = y^2 + 5y
=》 14y - 10x = y^2 + 5y...eqn 3
subst x = y-3 in eqn 3
=》 y^2 + 5y - 14y + 10y -30 = 0
=》 y^2 + y - 30 = 0
solving the eqn
y = 5 thus x = 2
subst y = x+3 into eqn 2
2x +14 = x +8
x = -6
3x - 5y + x + 2y....combine like terms
4x - 3y
(20*18)*5
Multiply the numbers inside the parenthesis first.
360*5
Multiply 360 by 5
