Question

(5x + 3y = 5
15y - 2x=-2

metodo de sustitución comprobado​

Answer 1

5x+3y=5
-2x+15y=-2

X=5-3y/5

-2(5-3y/5)+15y=-2
-10+6y/5+15y=-2
-10+6y/5+75y/5=-10/5
-10+6y+75y=-10
6y+75y=-10+10
81=0
Y=0/81
Y=0

X=5-3y/5
X=5-3•0/5
X=5-0/5
X=5/5
X=1

X=1
Y=0

COMPROBACIÓN:
5x+3y=5
5•1+3•0=5
5+0=5
5=5

15y-2x=-2
15•0-2•1=-2
0-2=-2
-2=-2
