For this case we have the following expression:

7x + 42 = 42

From here, we must clear the value of x.

For this, we apply the following property :

  • <em>Substraction property of equality:</em><em> Subtract the same number on both sides of equality. </em>

We have then:

7x + 42-42 = 42-42\\7x = 0

Answer:

he used Substraction property of equality

Solve the equation: sin(2x)= sin x
Anna [14]

Answer:

Below

Step-by-step explanation:

sin(2x) = 2 ×cos(x)× sin(x)

● sin(x) = 2 × cos(x) × sin(x)

● 2 × cos(x) = 1

● cos (x) = 1/2

So we can deduce that:

● x = Pi/3 + 2*k*Pi

● or x = -Pi/3 + 2*k*Pi

K is an integer
