Answer 2

The value of x is 3.75

GIVEN:- 4x-15=0

TO FIND:- solution for x

SOLUTION:-

• The linear equation in one variable is an equation which is expressed as a form of ax+b = 0, where a and b are two integers, and x is a variable which has only one solution.

• In the given questions 4 and 15 are two integers and x is a variable which has only one solution. We need to find one solution for x.

According to the question,

$4x-15=0$

When we shift any integer or variable from one side to another then the sign changes.

$4x = 0 + 15 \\ 4x = 15$

Dividing both sides by 4

$\frac{4x}{4} = \frac{15}{4} \\ x = 3.75$

To check whether the answer is correct or not, we'll substitute the value of x in LHS

$4x - 15 \\ = (4 \times 3.75) - 15 \\ = 15 - 15 \\ = 0 = rhs$

LHS = RHS =0

Hence, the value of x is 3.75
