Answer:
Move all terms not containing x to the right side of the equation.
Add 5 to both sides of the equation.
2x=7+5
Add 7 and 5.
2x=12
Divide each term by 2 and simplify.
2x/2=12/2
Divide x by 1.
x=12/2 => x=6
Step-by-step explanation:
12/2=6
You have to do the same thing to each side and try and move all the numbers to one side, leaving x alone so:
2x-5=7
+5:
/2:
x=12/2
x=6
10
For x=2, this is ...
5·2 = 10
