Question

if x\-3 = 5, what is the value of x?

Answer 1

Answer:

Solution : If 2,5,x are in proportion i.e. Substitute, Therefore, the value of x is 12.5.

Step-by-step explanation:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Explanation:

Given: x+3=5 .

Subtract 3 from both sides.

x+3 −3 =5−3.

∴x=2.

At x = 0 the function is undefined, because there is a zero denominator.

Answer 2

Answer:

x= -15

Step-by-step explanation:

1. x/-3 = 5
2. x = 5×(-3)
3. x = -15

this is a correct answer
