Question

What is the solution to the system of equations?

Answer 1

Answer:

The solution is the point (6,-8)

Step-by-step explanation:

we have that

The first equation is $y=(1/3)x-10$ instead $y=x-10$

$y=(1/3)x-10$ -----> equation A

$2x+y=4$ -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x

$2x+[(1/3)x-10]=4$

$(7/3)x=14$

$x=6$

Find the value of y

$y=(1/3)(6)-10=-8$

therefore

The solution is the point (6,-8)
