Answer:

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

[tex]y  = -\frac{5x}{4}[/tex]-----------------------(1)

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

[tex]y  = -\frac{5\times 6}{4}[/tex]

[tex]y  = -\frac{30{4}[/tex]

y = -7.5
