Solve the system of equations by the substitution method.

x+2y=-4
3x+5y=-14

a.
the solution set is { ? }
(type an ordered pair.)
b.
there are infinitely many solutions. the solution set is {(x, y) | ? }
(type an equation.)
c.
there is no solution. the solution set is empty set.

Option A

The solution set is (-8,2)

Step-by-step explanation:

Given is a system of equations as

We have to solve this by substitution method

Consider the first equation and write x in terms of y

" alt="x=-2y-4" />" />

Substitute in II equation as follows:

The system has a unique solution and the solution set is

(-8,2)

step-by-step explanation:

show the !

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
