Answer: 9.25
Step-by-step explanation:
Given equation : [tex]5x + 2y = 20[/tex]
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
[tex]5(0.3) + 2y = 20\\\\\Rightarrow\ 1.5+2y=20[/tex]
Subtract 1.5 from both sides .
[tex]2y=18.5[/tex]
Divide both sides by 2 .
[tex]y=9.25[/tex]
Hence, the value of y= 9.25
