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

Answer:
this is not a equation.
Step-by-step explanation:
sorry. Do you mean y+7=-3x or something?
<span>Divide the first term of the numerator by the first term of the denominator, and put that in the answer.Multiply the denominator by that answer, put that below the numerator.Subtract to create a new polynomial.
Hope this helps. :)
