Answer:
The answer for the unknown would be:
-12
Step-by-step explanation:
This is because ,
5n+26=19
5n+26=19
31n-31n=19-31n
therefore, (unknown) n= -12
The number will be -1.4 such that the sum of 5 times and 26 is 19.
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Let's say that number is x
Then,
5 times = 5x
So,
5x + 26 = 19
5x = -7
x = -7/5 = -1.4
Hence "The number will be -1.4 such that the sum of 5 times and 26 is 19".
