Find the solution of this system of equations -x-4y=37 -2x-4y=-53

Lelu [443]

Answer:

Final answer is x=90, $y=-\frac{127}{4}$

Step-by-step explanation:

Given equations are:

-x-4y=37 ...(i)

-2x-4y=-53 ...(ii)

multiply (ii) by -1

2x+4y=53 ...(iii)

Add (i) and (iii)

x=90

plug value of x=90 into (i)

-x-4y=37

-90-4y=37

-4y=37+90

-4y=127

$y=-\frac{127}{4}$

Hence final answer is x=90, $y=-\frac{127}{4}$
