2x+8=16 //solving tow-step equations// show work pls < 33

Your goal is to isolate the variable (x)
2x+8=16

Use the opposite sign to eliminate 8 from the left side (1st step to isolate x)
What you do to one side you must do to the other so:
2x+8-8=16-8

Simplify
2x = 8

Now use the opposite sign of 2x to isolate x (in this case division is the opposite of multiplication, 2x represents 2•x so 2x/2 will cancel it out)
2x/2 = 8/2

Simplify
x = 4
