Answer:

when x=3 the value of y is 9

Step-by-step explanation:

6.4x+2.8y=44.4, when x=3

6.4x+2.8y=44.4

To find y when x=3, plug in 3 for x in the given equation

6.4x+2.8y=44.4

6.4(3)+2.8y=44.4

19.2+2.8y=44.4

Subtract 19.2 on both sides

2.8y=25.2

Divide both sides by 2.8

y=9

So when x=3 the value of y is 9
