Three times a number x increase by four is equal to five times the number x which equation can be used to solve for x

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.
