Question

can someone help with this pls, I don’t get the instructions at all.

Answer 1

Very easy.
You need to move all x to one side and the number to the other side.
But if you move, the sign will change (- to +, and + to -)
-25+6x = -5+2x
6x -2x = -5 +25
4x = 20 /4. (Now divided by x number)
X = 20/4
X = 5
