The value of n if the value of a increases by 2 and the value of b decreases by 1 is 3a+ 2b -3.
What is Algebra?
Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
In algebra, these values are often represented with symbols such as x, y, z, p, or q, and these symbols are called variables. Further, these symbols are manipulated through various arithmetic operations of addition, subtraction, multiplication, and division, with an objective to find the values.
Given:
n= 3a + 2b -7
Now, if a increase by 2 and b decreases by 1.
n= 3( a+2) +2 (b-1) -7
n= 3a + 6 +2b - 2 - 7
n= 3a+ 2b -3
Hence, the value of n is 3a+ 2b -3.
