when I try to solve the equation 9x-5y=4, my answer is y=9/5+4/5. is this correct because I am having trouble trying to do a table of values for this equation.
No.
y=9x/5 - 4/5
check the signs.
thanks for your help.
since the answer is a fraction
y=9x/5-4/5, is it possible to create a table of values. for instance if I use -4
9(4)/5 - 4/5
36/5 - 4/5
7.25-4/5 =3.25/5 or .65
To solve the equation 9x - 5y = 4, you need to isolate either x or y. Let's solve it for y.
Step 1: Start with the original equation: 9x - 5y = 4.
Step 2: Move the term with x to the other side of the equation by adding 5y to both sides: 9x = 5y + 4.
Step 3: Divide both sides of the equation by 5 to isolate y: (9x)/5 = y + (4/5).
Step 4: Rearrange the equation to solve for y: y = (9x)/5 + (4/5).
So, your answer y = (9x)/5 + (4/5) is correct.
To address your difficulty with creating a table of values for this equation, you can choose any values for x and then calculate the corresponding values for y using the equation. For example:
Let's say x = 1:
y = (9(1))/5 + (4/5)
y = 9/5 + 4/5
y = 13/5
Similarly, you can choose other values for x and calculate the corresponding values for y. This will enable you to create a table of values for the equation 9x - 5y = 4.
