Rendering math...While solving an equation, Wayra made some mistakes. Her solution is given below. Please help her to identify t
solong [7]

Answer:

<em><u>According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.</u></em>

<em><u>She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z</u></em>

Step-by-step explanation:

Given the equation solved by Wayra expressed as;

Step 1: 13(z+6) = 4(z-3)-5z

She is find the value of z from the equation;

Step 2: Open the parenthesis using the distributive property;

13(z+6) = 4(z-3)-5z

13z + 13(6) = 4z - 4(3) - 5z

13z + 78 = 4z - 12 - 5z

Step 3: Simplify

13z + 78 = 4z - 5z - 12

13z + 78 = -z -12

Step 4: Collect the like terms;

13z + z = -12 - 78

Step 5: Simplify the result

14z = -90

Step 6: Divide both sides by 14

14z/14 = -90/14

z = 6.428

<em><u>According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.</u></em>

<em><u>She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z</u></em>

Is it ever too late to save for retirement?
Mekhanik [1.2K]

It can be too late to save for retirement. You want to begin saving at least 45 years before you plan to retire.

<h3>When to start savings for retirement?</h3>

Retirement is when labour stops working at a regular job. When a person retires, they would have a reduced source of income. This is why it is important to save for retirement. The earlier one starts to save for retirement, the more money the person would have when they retire.
