Question

metodo de igualacion 5x - 4y =2 2x + 3y = 17/4
ayuda porfa ​

Answer 1

Explicación paso a paso:

5x - 4y =2 2x + 3y = 17/4

x= 2/5+4y/5 x=17/8-3y/2

x=x

2/5+4y/5 = 17/8-3y/2

4y/5+3y/2=17/8-2/5

y(4/5+3/2)=(5×17 - 8×2)/(5×8)

y((2×4 + 5×3)/(5×2)) = (85-16)/40

y(8+15)/10 = 69/40

y 23/10 = 69/40

y=(69/40)/(23/10)

y=(69×10)/(40×23)

y=690/920

y=3/4

y=0,75

para x

x= 2/5+4y/5

x= 2/5+4(3/4)/5

x=2/5+12/20

×=(20×2 + 12×5)/(5×20)

x=(40+60)/100

x=100/100

x=1
