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
this an example problem of mixture problem in algebra
since the total amount of the container is 3.2, and let x be
the amount of the solution to be withdrawn.
So the amount of the solution left is (3.2 – x), it also the
amount of the 100 % solution.
0.354(3.2 – x) + 1*(3.2 – x) = 3.2*(0.733)
Solving for x = 1.47 liters is withdrawn
Plug in -5 where x is and 2 where y is
(-5 + 3, 2 - 1)
The new point is at (-2, 1)
hope this helps
