2x+6=2x+6

x принадлежит R

2. 4(x-5)=4x-20

4x-20=4x-20

x принадлежит R

Answer 2

Let's simplify each expression step by step:

1. 2(x + 3) = 2x + 6 Expand the expression on the left side using the distributive property: 2 * x + 2 * 3 = 2x + 6 Now, simplify: 2x + 6 = 2x + 6

The equation 2(x + 3) = 2x + 6 is an identity, which means it is true for any value of 'x'.

2. 4(x - 5) = 4x - 20 Expand the expression on the left side using the distributive property: 4 * x - 4 * 5 = 4x - 20 Now, simplify: 4x - 20 = 4x - 20

Similarly, the equation 4(x - 5) = 4x - 20 is also an identity and is true for any value of 'x'.

In both cases, we get the same expression on both sides of the equation, so the solution for 'x' is not restricted to any specific value. The equations are true for all real numbers 'x'.
