Answer: 
Three times a number x increase by four is equal to five times the number x. Equation x – 2 = 0 can be used to find the value of x. 
Solution: 
Given that three a number x is increased by 4
We need to find the equation. 
Three times of number x means 3x 
Increase by 4 means addition of 4 = 3x + 4 
Lets say 3x +4 is expression 1 
Five times of x is 5x . let it be expression 2. 
 Given that expression 1 and expression 2 are equal. 
So 3x + 4 = 5x 
5x – 3x + 4 = 0 
2x – 4 = 0 
x – 2 = 0 
Hence equation x – 2 = 0 can be used to find the value of x.
