x = 4
Step-by-step explanation:
We know that,
A parallelogram is a quadrilateral whose opposite sides are parallel.
Then the value of x will be,
→ 5x - 16 = 4
→ 5x = 4 + 16
→ 5x = 20
→ x = 20/5
→ [ x = 4 ]
Verification of the value of x,
→ 5x - 16 = 4
→ 5(4) - 16 = 4
→ 20 - 16 = 4
→ 4 = 4
→ [ LHS = RHS ]
Hence, the value of x is 4.
