Chapter 3: Q4. (page 127)

Solve the equation. Check your solution.3x+2x=25

Short Answer

Expert verified

The solution for the equation 3x+2x=25isx=5 .

Step by step solution

01

– Separate the variable and constants

Write the original equation and separate the variable and constants.

3x+2x=255x=25

02

– Solve for x

Now, divide both sides of the equation by 5.

5x5=255x=5

Therefore, the solution of the equation isx=5 .

03

– Check the solution 

To check the solution, write the original equation and substitute the value ofx.3x+2x=25

Now, substitute x=5and check the result.

3(5)+2(5)=2515+10=2525=25

As the left-hand side is equal to right hand side, this signifies that the solution is correct.
