6.4(x)+2.8y=44.4
6.4(3)+2.8y=44.4
19.2+2.8y=44.4
2.8y=25.2
y=9

To calculate this kind of problem, you must first convert the said equation to a form that could be the solution in getting the value of Y and the solution would be Y = (44.4-6.4X)/2.8. and the possible value of Y based on the formula, is 9. I hope this would help.
