What is the value of y in the equation when x=3? Image below.
Accepted Solution
A:
Answer:9Step-by-step explanation:We need to first plug in 3 into the place of "x" and then do some algebra and solve for the value of y. The steps are shown below:[tex]6.4x+2.8y=44.4\\6.4(3)+2.8y=44.4\\19.2+2.8y=44.4\\2.8y=44.4-19.2\\2.8y=25.2\\y=\frac{25.2}{2.8}\\y=9[/tex]Hence, the value of y is 9
