Answer:
x = 5
Step-by-step explanation:
2x -4 = 6
Add +4 on both sides
2x = 10
Divide by 2
x = 5
Answer:Solution
=5
Step-by-step explanation:
Add 4to both sides of the equation
2x−4=6
2−4+4=6+4
Simplify Add the numbers
2=10
Divide both sides of the equation by the same term
2x=10
22=10
Simplify
Cancel terms that are in both the numerator and denominator

Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
