Solve the system of equations by graphing. x+y=-9 4x+y=-19

For this case we have the following system of equations:

We multiply the first equation by -4:

We have the following equivalent system of equations:

We add the equations:

We find the value of the variable "x":

Thus, the solution of the system is:

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
