Question

Solve each equation. (Lesson 2 - 2)

$1.25y=4.375$

Short answer

The solution of the given equation is$y=3.5$.

Step-by-step solution

Step 1. Apply the concept of multiplication and division of equality.

An equation is an expression containing two quantities separated by a = symbol.

Finding a solution to an equation involves separating the variable on one side of the equation and numbers on the other side.

We can multiply or divide by the same quantities on both sides of the equation for separating the variable on one side of the equation and the numbers on the other side.

Step 2. Solve the equation for the solution.

We have the equation $1.25y=4.375$, we divide by 1.25 both sides of the equation as shown:

$\begin{array}{l}\frac{1.25y}{1,25}=\frac{4.375}{1.25}\\ y=3.5\end{array}$

Thus the solution of the given equation is$y=3.5$
