Answer:
42=7(z-3)
We simplify the equation to the form, which is simple to understand
42=7(z-3)
Reorder the terms in parentheses
42=+(+7z-21)
Remove unnecessary parentheses
+42=+7z-21
We move all terms containing z to the left and all other terms to the right.
-7z=-21-42
We simplify left and right side of the equation.
-7z=-63
We divide both sides of the equation by -07 to get z.
z=9
Well if you're solving for x this would be rather simple. 7x +1=68 , then you'd minus 1 from both sides. 7x = 67 then divide 67 by 7. The answer isn't a whole number so x would either be 67/7 or 9.57.. etc.
