Ilia_Sergeevich [38]

Answer:

76w + 17

= 35 + 28w + 48w - 18

= 28w + 48w + 35 - 18

Is 9 a solution to the equation 21=3p-5? Show work
Dmitry_Shevchenko [17]

Answer:

No

Step-by-step explanation:

21 = 3p - 5

<u>Step 1</u> : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

<u>Step 2</u> : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.
