What is the value of y in the equation 5x+2y=20 when x=.3

y = 9.25

Step-by-step explanation:

I'm going to assume when you typed x=.3, that it is x = 0.3 and the "." is not a typo.

given:

5x+2y=20  (rearranging to express y in terms of x)

2y = 20 - 5x   (divide both sides by 2)

y = 10 - (5/2) x

When x = 0.3, substitute this into the equation

y = 10 - (5/2) x

y = 10 - (5/2) (0.3)

y = 10 - 0.75

y = 9.25
