Question

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?

Answer 1

Answer: 9.25

Step-by-step explanation:

Given equation : $5x + 2y = 20$

To find the value of y at x= 0.3, we need to first substitute the value of x= 0.3 in the given equation.

Now, Substitute x= 0.3 in given equation, we get

$5(0.3) + 2y = 20\\\\\Rightarrow\ 1.5+2y=20$

Subtract 1.5 from both sides .

$2y=18.5$

Divide both sides by 2 .

$y=9.25$

Hence, the value of y= 9.25

Answer 2

Y=9.25 (short answer but hope this helped u)
