If the equation is 5x+4y and x is 6 what is y

The value of y is -7.5

Step-by-step explanation:

Given:

equation = 5x+4y

x = 6

To Find:

The value of y

Solution:

We can find the value of y by substitution method.The substitution method is a way of solving a system of equations by expressing the equations in terms of only one variable.

The substitution method for solving systems of equations is a way to simplify the system of equations by expressing one variable in terms of another, thus removing one variable from an equation.

Now

5x + 4y

5x = -4y

-----------------------(1)

on substituting the y value in the equation (1),

y = -7.5

Khalid and Sue's Height together is 126 Inches. The difference is 6 inches, so therefore you subtract 6 from the total getting you 120 Inches. You do this with all of the problems for example: The first one. Sue is 72 inches and Khalid is 54. Add them together and subtract them by 6 to get your final answer. Please DO NOT quote me on this lol. This is how I read the question. I think this is right but I am not absolutely 100% sure. Hope this helps.
