Question

i need help with this math

Answer 1

Answer:

(-0.6, 8.4)

Step-by-step explanation:

so first, we have to find out what x is. because y is equal to itself, we can substitute to get

$x+9=-4x-6\\5x+9=6\\5x=-3\\x=-\frac{3}{5}$

now we can plug in the value of x to find y

$y=-\frac{3}{5} +9\\y=8\frac{2}{5}=8.4$

your answer is written in the form (x,y) so the answer is (-0.6, 8.4)

Step-by-step explanation:

Hopefully this helps you!

~ Lets solve:

Use one equation to find an expression for one of the variables in terms of the other variable. Then substitute that expression in place of that variable in the second equation. You can then solve this equation as it will now have only one variable.
