What is equation?

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. Solving this equation, we get the value of the variable x as x = 7.

Here,

Let her regular pay be x and overtime pay be y.

8x+4y=160

y=x+10

8x+4(x+10)=160

8x+4x+40=160

12x=120

x=10

y=x+10

=10+10

=20

Kelly receives a regular pay rate of $10 and a $20 overtime pay.
