Answer:

x=10, y=-5

Step-by-step explanation:

2x+3y=5, y= 5-x; change y to 5-x:

2x+3(5-x)=5

2x-3x+15=5

-x=5-15

-x=-10

x=10

=>y=5-x=5-10=-5

Since x=8y, subsitute 8y for x in other equation

y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47
\frac{11}{47}=y
subsitute taht for y to find x

x=8y
x=8(\frac{11}{47})
x=\frac{88}{47}



x=\frac{88}{47}
y=\frac{11}{47}
in (x,y) form
(x,y)
(\frac{88}{47},\frac{11}{47})
