Jansen is 8 years old when Eric is four fewer than two times Jansen's age and their combined ages are twenty.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7. A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is utilized.
Here,
Let x be the age of Eric and y be the age of Jansen.
x+y=20
x=2y-4
2y-4+y=20
3y=24
y=8
