Question

Solve for w.
-6w + 1 = -11

  1. 2
  2. 1.2
  3. 12
  4. -2

hintHint:

Use two step process to solve 

First step be  subtraction 

And second step be division  .
 

The correct answer is: 2


    Given -6w + 1 = -11
    Solving using two step process  .
    Step 1 :Subtract 1 from each side.
    -6w + 1 - 1 = -11 -1
    -6w = -12
    Step 2 : divide both side by 6
    -6w/6  = -12/6
    -w = -2    ->   w = 2
    w = 2 , is the solution .

    First step be either addition / subtraction 

    if +ve sign is there in lhs with the number then subtract this number to both sides .

    if -ve sign is there in lhs with number then  add this number  to both side 

    And second step be division or multiplication ,

     After the above process if lhs variable is in multiply  , divide the number to both sides .

    After the above process if lhs variable is in divide multiply the number to both sides .

    6 increased by m is 18.

    In this question, we have to find algebraic equation of 6 increased by m is 18. If some thing like written x is increased by y then it is say that x + y ,If “ increased by” is given then it is addition. Like increased by , sum of, more than, the total of ,plus , add etc then it is addition in algebraic expression.

    James earned a total of $900 last week. This total was $10 less than five times the amount he earned last week. Find the amount of money James earned last week.

    In this question, we have to write the equation. Here less than is given that means subtraction. If subtract, subtract from, difference , between, less, less than, exceeds , etc words are used then it is always subtraction between two numbers.
