Chapter 1: Q32. (page 31)

Solve each equation. Check your solution

2b+4=48

Short Answer

Expert verified

The solutions of the equations is 20 or -28

Step by step solution

01

Step1- Order for solving the equation

To evaluate any equation involving more than one operation, follow the below order operation

  • First assume the case one in which the equation be x=y.
  • Secondly assume the case two in which the equation be x=-y.
  • Solve the equations of both the cases to find the value of algebraic expression.
  • After finding the two values of algebraic expression, put the value in the original equation and check the solution.

Step2- Solve the equations  

Case1- x=y

2b+8=482b=48鈭�8b=402

Case2- x=鈭�y

2b+8=鈭�482b=鈭�48鈭�8b=鈭�562

03

Step3- Check the solutions

Put the value of b=-28 in the equation 2b+4=48

2|鈭�28+4|=2|鈭�24|=2脳24=48

Put the value of b=20 in equation 2b+4=48

2|20+4|=2|24|=2脳24=48

The solution is 20 or -28. Hence, the solution set is (20,-28).
