Answer:
0.2
Step-by-step explanation:
Or 2/10. is that right?
7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
Given :

Answer:
7.324840764
Step-by-step explanation:
23/3.14=7.324840764
This is a simply problem. Just divide both sides the coefficient of x. Which is -2.
And the answer will be x = -4
