Solve by substitution or elimination 5x+3y=-15 -8x-2y=10

x=0, y=-5

Step-by-step explanation:

The system is

(1)  5x+3y=-15  

(2) -8x-2y=10

Let's solve it by elimination.  In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated

Multiply (1) by 2 and (2) by 3

(1) 10x+6y=-30

(2) -24x-6y=30

Add the two equations

10x-24x+6y-6y=-30+30 > -14x=0>x=0

Now replace this value in any equation, for example in (1)

6y=-30 > y=-30/6> y=-5
