In the figure, ABCD is a parallelogram. Given that OD = 5 cm and AC is 2 cm less than BD. Find OA.
Given a parallelogram ABCD. Complete each statement along with the definition or property used.
Solve: 2(3x+1) -5x =
First opening the brackets,
Now, the equation is
Transposing 2 to RHS and -4x to LHS, we have
or
or (Dividing both sides by 5)
∴
Check: LHS = 2(3x+1) -5x
=
=
=
=
RHS =
=
=
=
=
∴ LHS = RHS
