Answer 1

2х+2х=80

4х=80

Х=80 : 4

Х=20

______________

Answer 2

$2x + 2x = 80 \\ 4x = 80 \\ x = 80 \div 4 \\ x = 20$

Answer 3

To solve the equation 2x + 2x = 80, we need to combine like terms on the left side and then isolate the variable x.

Combining like terms, we have:

4x = 80

Now, we can isolate x by dividing both sides of the equation by 4:

(4x)/4 = 80/4

x = 20

Therefore, the solution to the equation 2x + 2x = 80 is x = 20.
