Question

Solve the following equation for x. 5x + 20y = 25

Answer 1

Answer:

x = 5 - 4y

Explanations:

The given equation is:

5x + 20y = 25

To make x the subject of the formula, take 20y to the other side of the equality sign:

20y becomes -20y on the other side

The equation becomes:

5x = 25 - 20y

Divide both sides by 5

`\begin{gathered} (5x)/(5)=(25-20y)/(5) \\ x\text{ = }(25-20y)/(5) \\ x\text{ = }(5(5-4y))/(5) \\ x\text{ = }5\text{ - 4y} \end{gathered}`
