Solve y = (2/5)x + 2 When x Equals 2: Linear Equation

Question

Find y y when x=2 x=2

y=25x+2 y=\frac{2}{5}x+2

Video Solution

Step-by-Step Solution

In this exercise, we are given the value of X, so we will substitute it into the formula.

It's important to remember that between an unknown and a number there is a multiplication sign, therefore:

y=25(2)+2 y=\frac{2}{5}\cdot(2)+2

y=45+2 y=\frac{4}{5}+2

Let's convert to a decimal fraction:

y=0.8+2 y=0.8+2
y=2.8 y=2.8

And that's the solution!

Answer

2.8 2.8
