Question

5x-y=-1 + -5x+3y=25 for two variable elimination quiz

Answer 1

Answer:

$(\frac{11}{5},12)$

Step-by-step explanation:

The system is

5x-y=-1

-5x+3y=25

We the two equations to get:

$5x+-5x+-y+3y=25+-1$

We simplify t get

$2y=24$

We divide both sides by 2 to get:

$y=12$

We now substitute y=12 in to the top equation to get:

$5x-12=-1$

$5x=11$

$x=\frac{11}{5}$
